[I haven't had time to digest this. But when Mike Rogers crunches a bunch of numbers, they get bumped. -KJ]
One of the better basketball blogs I've started following -- "better" is contingent on the fact that you enjoy some heavy math and basketball nerdery -- is the Basketball Distribution blog penned by Nathan Walker. I'm not an NBA fan, but he dabbles in college data as well.
Today he posted something he calls Offensive Decision Percentage (OD%). Looking it over, it seemed simple enough and I figured that with some spare time today, I'd throw this together for the Big Ten. I used the College Basketball section of the Sports Reference empire to grab the raw stats for every player in the Big Ten. Plug-and-chug and away we go.
Firstly, this data is for the entire season. Secondly, I imposed a minimum of 350 minutes played (average from all of the players is around 366 minutes this year, so 350 seemed like a decent cut off). Below are your top 15 "decision makers" in the Big Ten this year.
Nary a Spartan in sight. In fact, 16th and 17th on the list are also Wildcats in Alex Marcofullio and Michael Thompson. As you can see, it's pretty guard-heavy, which one would expect.
Now, your MSU Spartans on the list, with the same 350 minute stipulation.
Draymond I'd expect to see atop the list (or near it), but I wouldn't peg Delvon Roe as being (marginally) in second place.
Now, this is all great and whatnot, but we don't have a baseline yet. Well, instead of just having the straight-average OD%, I calculated the average for each position I used -- Forwards, Guards, Wings which, again, were categorized based on player's height. I only did this because after I grabbed all the data, I realized I was skipping over the listed position on the Sports-Reference page.
Armed with this, I came up with OD+, which is Adjusted Offensive Decision Percentage. It's adjusted for the positional average -- can we really hold forwards and guards to the same 'decision making' standards? I don't think so -- and puts it on a scale where 100 is the average and each point above/below that is equal to 1% better than average.
Using that, here are the top 10 guards.
Again, nary a Spartan in sight. Purdue's well represented as are the Badgers. Not surprising. Darius Morris shines for the Wolverines. He ranked well in PORPAG I posted yesterday and this might help explain that to a degree.
And now Ohio State joins Purdue as teams with multiple guys in the top ten. Diebler -- who I'm 90% sure came in the same recruiting class as Scoonie Penn and Michael Redd -- has a sizable lead on teammate David Lighty. You had to know Draymond would rate in the top five or so in this metric for his position.
And, finally, the forwards:
A couple Wildcats, Illini, Buckeyes, and no Spartans. Did you know that Bill Cole has a 50% minute percentage for Illinois and leads the entire nation (scroll down to 'all players) in Offensive Rating? Me neither. He's got the third best turnover rate in the country at 7.7% draws one more foul than he commits per 40 minutes, and has a 66.4 true shooting percentage and 64.8 effective field goal percentage. He's been a beast for Illinois.
Now, the top 20 in all positions, sorted by OD+:
Depressed enough between this list and the PORPAG numbers and, well, witnessing the games on television (or in person) yet? At least Draymond's there.
All Spartans, minimum of 100 minutes (to include guys like Nix and Sherman).
Another huge cliff from Draymond to anyone else in a metric. I'd like Lucas to rate better than he does. I was kind of shocked he is below-average. Considering the season, though, I guess it's not too surprising. Appling and Summers really haven't been good -- not shocked given the relative lack of assists that Summers dishes out.
In case you were interested, here's the baseline OD% I got for each position:
F - .515
G - .529
W - .483
