Enjoyable game...until it wasn't. It was fun while it lasted, but when they started to miss front ends of 1-and-1s, their confidence tanked, and they couldn't do much right after that. Those are the things that have hurt them the most this year: free throw shooting and horrific stretches within games. Purdue is way too good a team for the Gophers to exhibit both of those elements and still expect to win.
Toward the end you could see that Pitino was pissed. Just guessing, but I think part of the reason is that he knew he could have played his hand out differently to keep his team in the game, and he screwed up. In particular, he should have tried to nip the Purdue rally by calling a timeout earlier, when it became apparent they were making their run. I was surprised at the time that he had such a sluggish trigger finger on calling a timeout and thought it was a potentially fatal tactical error as it was occurring.
