Tourney face. [Fuller]
Beilein teams go further in the tournament than their seeds. This is known. We've repeated it so often that smart bracketeers even calculate it into their expectations. I've saved the "why" and "wherefore" of this effect for a roundtable question since that gets into the basketball strategy stuff that I'm weak in.
What I can do is build a pivot table out of multiple bits of data; in this case it was lots of schmearing and pasting, column breaks, and vlookups from sports-reference.com's bracket history and annual coaches records. The important lesson here is you're supposed to know it was hard.
UPDATE: Here's the raw data.
The first thing I tried was straight-up expectations by seed: top seeds are expected to get to the Final Four, 2-seeds to the Elite Eight; 3- and 4-seeds to the Sweet Sixteen; 5-, 6-, 7- and 8-seeds to the round of 32. The results had Beilein #5 after Brad Stevens of Butler, Sean Miller, and some Mizzou coaches who often had 9 seeds. That suggested there's a problem with my figuring:
I'm expecting 9 and 10 seeds to never advance so they're always in the positive; every time an 8 loses to a 9 it's a hit. The actual distribution is, unsurprisingly, progressive:
With over 1300 teams in my study there's very little deviation from the logarithm. It suggests, for all our complaining, that the committee does a pretty good job.
|Seed||Exp Wins||Seed||Exp Wins|
Since I'm a history major who had to re-teach himself exponential functions this morning (if predicting basketball games required encyclopedic knowledge of Plantagenets I'd have Ken Pomeroy's job) please go easy on me if I dispense with the other stuff and just use the values Excel returned as a base expectation of tournament victories for each seed (at right). The formula according to Excel:
y= 1.1634Ln(x) + 3.2127
With an expectation for victories now I can get a reasonable comparison versus that, for example a 2-seed that advances to the Sweet 16 has 2 victories minus 2.41 expected = 0.41 fewer wins than they should have. The last thing was to remove coaches who've been to fewer than five tournaments. We're ready to rename March after a coach. But which one?
[Don't act all surprised; you knew I'd make you jump for it.]
