I think the visceral reaction to the UCLA loss is for a few reasons:
1) Most of our losses before this make sense; Uconn and Bama we were still figuring things out, Nebraska was a close loss on the buzzer that happened to be against a very good team- MSU- tough environment, very good team, no Kylan. Wisconsin- tough to stomach- but we played 6 guys and still should've won- Wisconsin is a solid team.
UCLA- there's no excuses anymore- not still "figuring things out", the team is fully healthy, we were and are the clearly more talented and better team, win and you likely lock down a 2 seed and give yourself a chance at a 1 seed, UCLA is a fine team- but was reeling from some awful losses, and to make matters worse- we come out and blow the doors off UCLA to go up 33-10. We then make history with the biggest choke/collapse in NCAA history for an AP top 10 team- so a true kick in the stomach result. Oh- and we lost on a last second layup- in which our defensive plan was questionable at best- and where the player didn't get stopped at all and had a nearly uncontested layup.
It's not that I don't think we are capable of beating Michigan- I realize full well that the eye test and analytics say we can beat them. BUT- we lost the UCLA game because of a lack of effort and intensity- best example would be Andrej bending over casually to get the lose ball under the basket, while 2 UCLA players go after it like their lives depend on it and one of them dives for the ball and saves it. We also gave up an offensive rebound on a flipping free throw.. in which the UCLA player then easily put it back for a layup- A FREE THROW offensive rebound and layup- what???????? Problem is- you can count a plethora of those in the game.
Our biggest weakness is our inability to guard quick guards and bigs that can pop- mostly because Tomi, Big Z, and Mirk are very poor perimeter defenders/defending in space. I'm deeply concerned about the tournament because you face... very good guards and often bigs that can pop- and guess what- some of the best coaches in the country who will literally attack Tomi, Z, and Mirk EVERY PLAY. And we have a coach (who does a ton of things well) but has shown to be a mediocre in game coach- in which I have very little confidence we will be able to adapt during the game. See Loyola, Uconn and more recent examples of MSU, Wisconsin, and UCLA...
I'm probably unfairly skeptical of this teams ability to beat Michigan because we are at the end of the season and are talking about the lack of urgency and effort in a MUST WIN GAME against an inferior opponent. That is deeply concerning- especially since we are an old team that should have the leadership to make sure we play with urgency.
