After Indiana beat Iowa last and Purdue beat Nebraska things were a little bittersweet. Sure, it sucks seeing your bitter rival clinch the outright Big Ten title (tying Purdue for the most all time), but they earned it. If you argue about a "weak schedule" you sound like an idiot because, well, Purdue’s wasn’t exactly much stronger. Also, you can’t argue anymore about Tom Crean’s coaching credentials. Yeah, he’s a little weird, but he rebuilt a program that was ashes and now has won two Big Ten titles in four years.
The truth is, Indiana earned this. As I always say, if you don’t want to bitch about something, don’t lose.
