Sure he loses his fair share too that he is supposed to win (as every coach does) but he wins tough games. Just last year he won at stanford, vs texas, at smc, and at usf. Losses at lmu and pacific were bad and while iowa state was a loss to a great team, he was outcoached in that game.

All in all, rose delivers some great wins pretty much every year. Off the top of my head, the nit season was probably the only year it didn't happen (until the nit)
