Numerology: The Good News

Posted by Kevin Arnovitz On November - 4 - 2009

If you speak to executives who use advanced analytics to make player personnel decisions, many of them will tell you a similar story about such stats:

We like to look at the performance of specific units as much as individual players.

Since opening night, the Clippers have fielded five units that have played collectively greater than 9 minutes:

Unit MP Off Rtg
Def Rtg ORR DRR
Davis-Gordon-Thornton-Camby-Kaman 76 103.8 99.3 28.9 76.2
Davis-Gordon-Butler-Camby-Kaman 53 115.7 100.0 40.0 70.4

Dave Berri: Optimistic With Caveats

Posted by Kevin Arnovitz On October - 19 - 2009

Dave Berri has a new post up at The Wages of Wins Journals prognosticating the Clippers as a vastly improved team in 2009-10.

Berri’s optimism is based on a number of factors:

  • Blake Griffin’s monster collegiate numbers translate well to the pro game. Assume — and it’s quite an assumption — Griffin puts up numbers commensurate to Tim Duncan’s rookie season (19.5 wins produced), when you subtract that from Zach Randolph’s 3.5 wins produced in 2008-09, that would still leave the Clippers short of .500.

Mike Dunleavy: Forebearer of Effective Field Goal Percentage

Posted by Kevin Arnovitz On September - 29 - 2009

I’d read recently on Kevin Pelton’s Statistical Analysis Primer that “Effective Field-Goal Percentage was invented by current L.A. Clippers Coach Mike Dunleavy.”

Dunleavy as statistical innovator came as some surprise because the Clippers aren’t regarded as an organization on the vanguard of advanced analytics. By Dunleavy’s own admission, he wasn’t looking to glean any rarefied knowledge about the basketball universe when he came up with effective field goal percentage. He was just trying to negotiate a fair contract in the latter half of his playing career.

Blake Griffin: Inside the Numbers

Posted by Kevin Arnovitz On June - 24 - 2009

I had a chance on Tuesday to look at some advanced numbers from Blake Griffin’s sophomore year at Oklahoma, and posted about it at TrueHoop:

  • The first thing that jumps off the page in Griffin’s report is the percentage of his offense that comes from post-ups — 44%. To put that in perspective, Al Horford came ouf of Florida with a 43% number, but you’d be hard-pressed to find many amateurs who get out of the 30s. Horford was a bit more efficient than Griffin on the block (1.11 vs. 1.00 points per possession), but Griffin’s number is still very strong. As the Synergy report states, “Blake’s proficiency in this area will not only produce a high percentage shots for his team when he goes to work on the block, it will also create open shots for his teammates when players are forced to leave their men to help defend Blake’s post-ups.”
  • Baron Davis, take note: Griffin’s numbers indicate that he moves as well off the ball as any big man we’ve seen in recent years. He recorded a whopping 1.5 points per possession on cuts. The reports says it all, “This indicates that Blake is active, has good hands, and knows how to score the ball attacking the rim. This is a valuable asset that produces easy scores and cause the defense to track yet another offensive threat. Combine a good passing point guard with Blake and his team will burn the defense in this type of offense.”
  • Griffin will need to spend a lot of time developing his jump shot. He generated only 0.64 points per possession on spot-ups. At Oklahoma, those opportunities accounted for only 2% of his offense, but at the pro level, he can’t be an elite power forward without some range.
  • Griffin is a terrific big man in transition, where he chalked up 1.32 points per possession. The comp here is Brandan Wright, who had similar success on the break at Carolina in 2007-08. If the Clippers can get stops and control the defensive glass (two big ifs), they’ll be able to use Griffin to get out of the offensive efficiency cellar — they finished 30th in the league last season.

There’s some other interesting stuff in the data. Griffin is an efficient scorer on both blocks. He works from the left block 51% of the time, and the right block 41% of the time, averaging 0.99 PPP and 1.01 PPP respectively. Once he gets the ball, Griffin prefers to spin baseline — which makes sense given that he hasn’t yet developed a face-up game. Expect to see defenders to cut off that baseline in his rookie campaign and force him to shoot from the middle of the lane.

When we talk about Griffin’s development as a pro, we spend most of our time discussing his shooting — but learning to play pick-and-roll basketball will be another vital piece to his maturation as a big man. Pick-and-rolls accounted for only 3% of his offensive possessions at Oklahoma last season, which isn’t abnormal at all.  Only a few college programs — like Texas and Ohio State in recent seasons — run a pro-style offense. Griffin has the quicks, athleticism, and body to be a phenomenal PNR player. Watching him cultivate that part of the game will be even more satisfying than watching him refine his jump shot — particularly as he and Eric Gordon establish a two-man game.
