I mean I just don't think Cal is as awful as some here think he is. For the most part I just think he made some terrible staff decisions that caused a recruiting dip. I also look at seasons like '17/'19 and can reasonably handle losing in the EE in games we could have won, just like we could have lost in '11 and '14. The last 3 years haven't been good at all...that's on Cal, no doubt. But I don't think he forgot how to coach...
Fwiw I am probably the biggest fan of Thiero on the board, going back to seeing him in a summer practice before he ever played a game here. I think he should have been playing over Edwards pretty much since day 1 if you are running a non-3 guard lineup.
All that said, people like to say Cal plays favorites and all this stuff. It just doesn't make sense. Go look at people he didn't play vs who he did over the years. The most common example given is BJ Boston. Ok, who the hell was he going to play? It is just silly IMHO.
