For whatever it's worth, I think he deserves far more criticism for CHANGING the league's championship criteria to put Ohio State in the football title game than he does for HOLDING to the league's criteria in naming Michigan the sole champion. But he set the precedent with one and then didn't follow it with the other, that much is true.
Everyone knows who the real 2021 champion was, even Hunter Dickinson himself. I don't lose a moment's sleep over that.
But anyway, it was absolutely the COVID thing. The Big Ten is a conference that settles things behind closed doors and speaks with one voice. That's what Jim Delany built. When the new guy screwed that up in such a high-profile fashion immediately, he was done, there was never any coming back from that.
