I would not get too caught up in players opinions with one exception - if the majority do not like the coach, that is an issue.
Players pick schools for the coach - so the expectation from day 1 is that they are going to like them and defend them. And your always going to have a few here and there who are unhappy because of outside issues or playing time, etc. So having a couple kids here and there who do not like the coach, is not a problem to me. By all accounts - from Beilein, to Wainwright, to now Mooney - players who played for them - like the coach.
I agree with Spider23 - even with more recent examples. Under Beilien - I thought we had a chance against everyone - BUT - i did feel like at times, if the shots were not falling early, you knew we were in trouble and probably uphill battle to win. Wainwright - always felt like we had a chance, because his teams were built on defense. The games and offense at times we ugly - but very rarely, if at all - did I feel like we never had a chance to win. Mooney - very similar to Beilein, if we start well, and are hitting shots - I feel good. But I always worry about that dry spell that Mooney's teams seem to always seem to experience where we go 3-5 minutes with little to no scoring, get behind and can't come back. So even when we are up 6 or 8 in the 2nd half, I worry we will not hold on.
