This will probably be a minority opinion, but - for better or worse - I really didn't see much last night that was uncharacteristic of a late season B10 game. The B10 tends to be on the rough side to begin with and college refs in general seem to get less whistle-happy as the season wears on, so it is what it is.
Once it's clear the refs are going to tolerate some rough stuff, it's up to you as a player/team to decide if you're going to wilt (like we did against NW, who I felt was very rough & the Hawks either had no interest or ability to match it), or if you're going to lace up your Nike's a notch tighter and go blow for blow with the other fellas (like we did last night, which was glorious to behold!)
