how does this happen?

I can't believe the finishes of the late games today. Crazy. And neither team I was rooting for won.
Texas won a shot that no one should make. Gonzaga lost on some plays no one should make. How do you let that happen? UCLA scored the final 11 points, and the 'Zags lose the ball going for the final shot.
I don't pick Gonzaga to go far anymore, after being burned the last few years, but at the half I was looking forward to the Memphis/Gonzaga matchup.
I'm glad Duke lost, but there aren't a lot of teams left I want to watch.
