It was a surprise for me. I don't live in Wisconsin anymore, so I can't report on the vibe over there for our disappointing start, but the few Wisconsin friends I still talk to regularly didn't give me the impression that people were calling for Coach's head.
Feels like there was some backroom political shit happening out of view of the players and fans
Wisconsin fans I've heard from say they were wanting to move on, and are surprised it happened now, but they are pleased, gives the Interim Coach a chance to show what he can do.
