The latest numbers that I've seen were 2013-14... Crean spent over $715K in recruiting expenses... sorry... the only one holding FCTC back was FCTC.
He had way too many misses (Jeremiah April, Tijan Jobe, Peter Jurkin, Bawa Muniru, Guy Marc Michel, Austin Etherington, Grant Gelon, Tim Priller, Bobby Capobianco, and the bad character wash-outs like Hanner Mosquera-Perea, Devin Davis, Jeremy Hollowell, the entire "Movement", save Yogi, and Stanford Robinson, Remy Abell). And Crean "screwed the pooch" with Luke Fischer who was run off by Crean's players. And then there were those who were "creaned", including Matt Roth and Maurice Creek.
I'm sure there are others... like Max Hoetzel - not sure where to list him...
Crean was his own worst enemy. For every "home run" recruit or diamond in the rough that panned out, there were 3 or 4 who had no business being invited to Bloomington ... and when you throw in the fact that he's a horrid bench coach, we get what we got - and IMO, WAY too much of it.
