Dan B's whole shtick this season has been playing up Brohm as the miracle-worker, and Purdue as "his" team. Going into the Gopher game, he was laying it on thick about what a great coach Brohm was. And then the Gophers beat Purdue soundly. So, Barreiro comes back with the tweet as a back-handed compliment to Fleck for beating 'super-coach' last week. I suspect Barreiro still thinks Brohm is a better coach, but the tweet was his way of admitting that Fleck won the match-up this season.
This still gets back to a basic contradiction. Fleck himself says "I'm not for everyone," but when fans or media members take shots at Fleck, his defenders get all bent out of shape over the idea that anyone could criticize their hero. Hey, Fleck is the one who admits that some people just aren't going to like him. Why can't his supporters grasp that same concept.
