The pressure of the moment destroys many warriors. Just like in the Auburn game...how does a player not know when running out on a desperation 3pt shot that the primary goal should be to not bump the shooter? Yet, it happened.
Even before that last 3-pointer by Virginia, TT was leaving shooters open, and they really haven't done that in prior tourney games. Yeah, maybe Hunter wasn't a great shooter, but he was on last night...TT needed to identify that and cover him. Even apart from Hunter, they left guys open, and they normally don't do that. They just made too many defensive mistakes...mistakes that they normally don't make.
Izzo pretty much said the same thing in his TT post-game interview. He said his team just made uncharacteristic mistakes, which I think is a polite way to say that they just didn't handle the pressure of the moment.
