2010-11 Raptor Charts Part II

New readers, please check out the basics before leaving any comments.

Yesterday I posted part one, which included both team and individual charts showing the game-by-game distribution of both field goal attempts and scoring efficiency (as determined by the formula PTS-FGA-0.5*FTA). Today I'll be posting the part two, which does the same for Net Possessions and "Helpers".

A player's Net Possesions is determined by the formula REB+STL-TO. This formula rewards those who gain possessions for their teams, and punishes those who give the ball away. Who do we think is going to show up first using this method?

2010-11 Raptor Charts Part I

New readers, please check out the basics before leaving any comments.

I have a couple of things to post today (with more to come in a bit). The first is a link to a piece about the "most harmful players" of the regular season by Ty Willihnganz over at Courtside Analyst (take a stab at why this article would be relevant to the Raptors). Ty also has posted his MWS Charts for every NBA team - go and take a look at Toronto's numbers. The overall numbers are very similar to Wins Produced - although by MWS, Bargnani looks even worse, Reggie looks even better, and Ed Davis looks more average.

I have also been working on various Raptor charts over the last few weeks. Several weeks ago, I looked at how the Denver Nuggets' FGA changed before and after the Carmelo Anthony trade, and the intention was always to apply the same technique to the Raptors at the end of the season. Well, the season has been over for the Raptors for a while now, so it's time to get this up.

2010-11 Raptors Season Review

New readers, please check out the basics before leaving any comments.


Now that the season is official over for the Raptors, it's a good time to review how the season went.

Team Overview:
Team Record: 22-60 (28th)
Eastern Conference Standing: 14th
Team Wins Produced: 23.3 (27th)
Point Differential: -6.28 (27th)

Even the brief numbers aren't pretty; in a little bit I'll take a deeper look at the team numbers, but for now let's just take a quick look. The Raptors finished with the 3rd-worst record in the league (2nd-worst in the East), behind only Cleveland and Minnesota. In terms of Wins Produced and point differential - both better indicators of team quality than Win-Loss record - the Raps finished with the 4th-worst numbers in the league.

Certainly not very happy numbers. And actually, even worse than the paltry amount of wins I predicted that the team would end up with (which was 28 wins). What happened to the Raptors this season? Well, it would make sense if I compared what I thought would happen against what actually happened.

The Regend and the Ninja: A Response (part II)

New readers, please check out the basics before leaving any comments.

On Saturday, Tom Liston of Raptors Republic - TrueHoop's Raptors' affiliate - wrote a column about Reggie Evans and James Johnson. In his column, Tom mentions that he has some problems with Wins Produced and my analysis of Evans and Johnson in the past. Specifically, Tom's main issues seem to be:

• Evans' WP48 is near the top of the league (currently at 0.356), but Reggie doesn't seem to belong with the other players (Kevin Love, Dwight Howard, Chris Paul, LeBron James, Dwayne Wade) at the top.
• If Wins Produced doesn't overvalue rebounds, and the only thing Evans' does well is rebound, why is Evans' WP48 so high?
• James Johnson is playing well in Toronto - "he’s pretty much exactly the same player" as he was during his rookie season. So why did I say that he probably wouldn't be a good player when Toronto traded for him?
• Wins Produced is one measure of player productivity among several, and one should "never rely on one metric to draw conclusions".

The other day I responded to these first two points. Today I'm going to tackle the last two.

Week 15 Auto WP numbers

New readers, please check out the basics before you leave any comments.


Hey, it's been a week, and I'm still around! What's going on?

Some good news for this week: Linas Kleiza is out for the season. Not only does that mean that someone else (hopefully someone more productive this time, like Wright) will get more minutes, but it might also be the explanation for why Kleiza has been so unproductive this year; in the past, Kleiza had been much better. There are also concerns about how the Raptors' training staff handled the injury, and the Raps seem to have a recent history of injury disputes with certain players. Oh well - what's a little more dysfunction for this franchise?

Here are the numbers for the season so far, which are Powered by Nerd Numbers (full spreadsheet here):

Week 14 Auto WP Numbers

New readers, please check out the basics before leaving any comments.


Well I'm back - and hopefully for good. After an eight day delivery delay, an OS crash, and a one day delay in the delivery of the new OS installation disk, my new computer seems to be up and running just fine.

For now.

Meanwhile, in a disturbing parallel, the Raptors - suffering through injuries and the return of unproductive players - have crashed as well. How bad has it gotten? In terms of record, the Raps are now in 14th place in the East, only ranking ahead of...the Cavs. In fact, the Raptors are 27th in the league standings, cavorting with the likes of the aforementioned Cavs, the Kings, the T-Wolves, the Nets, and the Wizards. Not only that, but the beloved "most consecutive games with at least one 3pt FG" streak finally came to an end, and the Mavericks are about to break the record, erasing Toronto from the record books forever.

Yes, it's been ugly lately.

But what do the WP numbers look like? Are the Raptors playing better than their record? Here are the numbers - as always, Powered by Nerd Numbers (full spreadsheet here):



Here are my thoughts:

• See all that red? Of the 21 players the Raptors have employed so far this season, ten - almost half of the roster - 47% - have produced in the negative range. "Oh well," you might say, "most of those players haven't played many minutes," and you'd be right: six of the ten haven't managed any more than 89 minutes played. Unfortunately, that also means that the remaining four have played significant minutes; Kleiza, Weems, DeRozan, and Bargnani (the current Four Horsemen) have combined for 4920 minutes of playing time, which is only 39% of the team's minutes.
• These four players have also combined to produce -4.9 wins. Yes, by playing these four unproductive players this many minutes, the Raptors have cost themselves almost five games in the standings.
• Barbosa gets a reprieve for now, as he is barely positive for the time being, but if you add him to the above numbers, you get five players producing -4.5 wins in 45.5% of the team's minutes. That is just an absolutely astounding level of putridity.
• Jerryd Bayless has not played well ever since his first few glorious games in a Raptor uniform; he's now a below average player over the course of his tenure with the Raptors. This is probably because he feels bad for defying my prediction that he won't be a productive NBA player, and is simply playing worse to make me feel better. Either that, or injuries, or small sample sizes, or some combination of the three.
• With all the injuries lately, the Raptors had to sign some fringe players to 10-day contracts and managed to acquire Alexis Ajinca (and the second round draft pick they sent to the Mavs to acquire Solomon Alabi) from the Mavs (in exchange for the rights to an old draft pick who will never play in the league). Although they have played limited minutes of the course of their careers, Dupree, Trey Johnson, and Ajinca have not looked like good players. Gaines is the more interesting case, as he was pretty decent when he played for the Jazz last year, but he hasn't shown anything so far this season.
• I like the idea of acquiring young centres on the cheap, but if you're going to do it, do it right and go after undrafted players, productive D-League players, or productive players from other leagues. Gaines was certainly worth the gamble, but - despite having impressive scoring averages - Trey Johnson was merely an above-average D-League player (WP48 0.150), and not even the best player on his team.
• The players who should be playing the most minutes: still Calderon, Bayless, Wright, Amir Johnson, Dorsey, and Davis.
• Add up the Wins and you get 14.9; since the Raptors have won 13 games, that means that they have been a little bit unlucky over the course of the season. Unfortunately, if you look exclusively at more recent numbers (thanks Arturo!), the Raptors are actually playing even worse than their record.
• Do I have to mention Bargnani's poor play? Last time I mentioned that his play was likely to get worse, and it has. He now has a comfortable lead over the other contenders for the Darius Songaila award. Is Bargnani a bust? Most definitely.

Player trends

Good:

• Ed Davis: 11 GP, AdjP48 +0.069, Wins +1.5
• Amir Johnson: 11 GP, AdjP48 +0.018, Wins +1.6
• Jose Calderon: 10 GP, AdjP48 -0.008, Wins +1.4

Meh:

• Julian Wright: 10 GP, AdjP48 +0.004, Wins +0.7
• Leandro Barbosa: 2 GP, AdjP48 0.000, Wins +0.3
• Linas Kleiza: 4 GP, AdjP48 -0.006, Wins -0.1

Ugly:

• Joey Dorsey: 6 GP, AdjP48 -0.034, Wins 0
• Alexis Ajinca: 3GP, AdjP48 --, Wins -0.1
• Sony Weems: 4 GP, AdjP48 -0.018, Wins -0.3
• DeMar DeRozan: 11 GP, AdjP48 -0.025, Wins -0.8
• Jerryd Bayless: 9 GP, AdjP48 -0.040, Wins -0.1
• Andrea Bargnani: 11 GP, AdjP48 -0.040, Wins -1.9
• Trey Johnson: 3 GP, AdjP48 --, Wins -0.2
• Solomon Alabi: 4 GP, AdjP48 -0.450, Wins -0.2

More posts to come over the next few days - I promise!

Week 11 Auto WP Numbers

New readers, check out the basics before leaving any comments.

Okay, so I'm late again this week - at least I can blame this one on not having a computer (the name of the company that is responsible for this travesty rhymes with bell). Here are the numbers (full spreadsheet here), which are Powered by (the new-look) Nerdnumbers:

Here are my thoughts:

• Calderon continues to play well (when he plays).
• Amir Johnson maintained his previous rate of production over his last five games.
• Joey Dorsey's production is still declining slightly, mostly due to his increased foul rate. And have I ever mentioned his terrible free-throw shooting? He really is the perfect replacement for Reggie Evans.
• Bayless has remained largely unchanged, although his FT rate is down more than half an attempt per 48 minutes.
• Ed Davis' production also declined slightly - his shooting is better, but his rebounding is down from 14.2 to 12.6 and his fouls are up (5.4 to 6.1). Luckily his blocks are up as well (1.8 to 2.5).
• Julian Wright continues to improve and has nearly matched the production of an average player. His AdjFG% is finally above 50% and his net possessions have increased by 0.7 per 48 minutes.
• Barbosa has once again left the red with improvements across the board (shooting, net possessions, and assists, blocks, and fouls). How long will he stay there? Your guess is as good as mine.
• Kleiza's production declined again, but at least he isn't hurting the team - he has a WP48 of 0.000. That is, if we believe that he spends approximately half his time at SG, which he doesn't, so his real numbers are somewhat worse.
• For all the recent talk that DeMar DeRozan has improved during his second year, his WP48 continues to remain in the negative range this season (at least last year he posted a WP48 of 0.026). But do you want to take a stab at what has increased for DeRozan this season? PPG and his scoring rate, of course. Even though his shooting percentages are down. When will people learn? DeRozan is Bargnani all over again.
• Meanwhile, Bargnani is getting...better? His AdjFG% and FT% are up and blocks and fouls have improved. While I'm happy at the reversal, it's likely only temporary; given that shooting percentages fluctuate over the course of the season, real improvement from Bargnani will have to come from the non-shooting aspects of the game (ie: rebounding).
• The team's most productive players right now, by position: Calderon, Bayless, Wright, Johnson, and Dorsey, with Davis as the 6th man.

Raptors Preseason Review #4 (of 4)

This article uses the Wins Produced metric to discuss the productivity of NBA players. This metric is based on box score statistics that are adjusted for other factors including pace, position and team. A general scale is given for these, and links to advanced explanations are listed at the bottom of the page.

Wins Produced per 48 Minutes (WP48) – The number of wins a player produces in 48 minutes of play. 0.100 is average and 0.250 is considered the “superstar threshold”. A player a WP48 of 0.000 produces no wins, and any player with a negative WP48 produces a negative number a wins (or, if you prefer, a positive number of losses)

For more information on the terms used in this post, please consult the Glossary of Terms.


After reviews #1, #2, and #3, here are how the preseason numbers ended up:



I've added some fancy colours to the per 48 minute columns - but please note that the colours are based on totals only and are not adjusted by position. For example: Bargnani doesn't fare so poorly in rebounding when compared to the team as a whole (he's yellow), but compare him to other centres and he'd be terrible (red). Anyways, how are the stats different from the last time we checked in?



Here are my thoughts about the last two games, as well as the preseason as a whole:

• Raptors' preseason MVP: Jarrett Jack. Runners-up: Dorsey, Kleiza, and Evans
• Raptors' preseason LVP: Andrea Bustiani. Runners-up: Calderon and DeRozan
• Of the players who played significant minutes, Kleiza and Johnson lowered their EWP48s (read: got worse) the most over the last two games
• Barbosa and Evans raised their EWP48s (read: improved) the most over the last two games
• Calderon, Banks, Alabi, and Bargnani ended up producing a negative number of wins
• Calderon watch: his best game of the preseason was against the Knicks (EWP48 0.397 and EWP 0.132)
• Calderon only did one thing well: rack up assists. But his shooting was terrible
• For another guy who's supposed to be good at shooting...Bargnani didn't shoot well at all
• Bargnani moved "up" to 11th least productive in the league during the preseason on a per-minute basis (according to Arturo). In terms of total wins produced, Bargani is 4th last, behind Marcus Thornton (2nd year player), Sharron Collins (rookie), and Kenny Hasbrouck (rookie). So...is Bargnani a bust yet?
• Bargnani's only game in the black this preseason was the second game against the Suns - every other game he was negative
• Bargnani accumulated a Win Score of exactly 0 in 216 minutes
• I'd prefer David Andersen to Bargnani - even excluding Bargnani's massive contract. Andersen was better in every area, except blocks and fouls
• Not news: Reggie Evans rebounds like a madman
• News: Joey Dorsey out-rebounded the madman
• Julian Wright was pretty good in limited minutes. He benefited from playing most of his time at SF
• Going by these numbers, the team's bigs are probably going to have foul trouble most games. Maybe it's time to acquire a decent centre?

There are other stories in those numbers, but those were the ones that spoke to me the most. If you spot any other interesting tales, let me (and others) know in the comments.

Raptors Preseason Review #2 (of 4)

This article uses the Wins Produced metric to discuss the productivity of NBA players. This metric is based on box score statistics that are adjusted for other factors including pace, position and team.

A player a WP48 of 0.000 produces no wins, and any player with a negative WP48 produces a negative number a wins (or, if you prefer, a positive number of losses) 

Here are the Raptors' numbers after four (of eight) preseason games:



As you can see, there have been a few changes in the team rankings. How have things changed?



Looking at the numbers, here are my thoughts:

• Notice the general trend of players with larger EWP48s becoming less productive, and the players with highly negative WP48s becoming more productive? That's regression to the mean. The players at the top were performing abnormally well, and the players at the bottom were performing abnormally poorly; it was only a matter of time before things normalized
• Productive players who played poorly over the last two games: Weems, DeRozan, Kleiza, and Dorsey
• Productive players who have stayed productive: Jack
• Unproductive players who continued to play poorly: Bargnani and Calderon
• Unproductive players who were productive: Evans, Dupree, Barbosa, Wright
• Jack had a huge game against the 76ers: EWP48 0.824, EWP 0.566
• Jack had a terrible game against the Bulls: EWP -0.359, EWP -0.195
• Kleiza had a terrible game against the 76ers: EWP -0.345, EWP -0.129
• Bargnani's best game so far: v. Bulls,  EWP -0.074, EWP -0.040
• Calderon's best game so far: v. Bulls,  EWP 0.001, EWP 0.000
• The last two games have been a better indication of how things are going to go during the regular season, because the Bulls will be a good team and the 76ers are going to be bad

Nothing is too far out of the ordinary for the Raptors so far, apart from the play of Jose Calderon. If he plays like this during the regular season, the Raptors are going to struggle to break 20 wins.

That's right - 20.

2009-10 Player Review: Julian Wright

I've already posted a little bit about Julian Wright already, but let's take a more in-depth look this time:

Deja vu, man

Wright was something of a disappointment in New Orleans. He was one of those rare rookies who managed to be an above-average player in his first season, only to regress rather substantially for two straight seasons. Let's look for some clues as to how he lost productivity:

He started off shooting the ball very efficiently, breaking 1.10 PPS. He followed that up with seasons of 0.94 PPS and 1.01 PPS; with such volatile shooting efficiency, it's difficult to predict where he'll end up next year. There are some clear trends, though - Wright is a poor free throw shooter, a poor scorer, doesn't take many FG or FT attempts; is a below-average rebounder, possession-getter, blocker, and passer; and is above-average with respect to steals, TOs, and PFs. For Wright to improve next season, he should try to improve his rebounding and increase his shot attempts (while maintaining or improving on the efficiency level he showed last year).

While his overall progression does not look good, he is only 23 years old and I have him penciled in for a WP48 of 0.050 next season - right around his career mark. It is entirely possible that the change of scenery will do him good and he will return to the rate of production we saw from him as a rookie; then again, it's also entirely possible that his downward trend will continue and he will enter into negative WP48 territory. Based on Wright's career so far, neither would be exceptionally surprising.
