I watched about 10 minutes of the game, before and after halftime, so I am entitled to a ill-informed opinion too. My 2 main thoughts:
1. "Shooting". Iowa shot badly, but a big piece of that was trying to shot over/around Baylor's tall guys. And of course Baylor, going for blocks, didn't rebound well so Iowa gets more shots that they can't get over/around those bigs. So I don't buy "had a bad night shooting" excuse -- a lot of that is credited to Baylor.
2. "Athleticism". Not even going to talk about vertical leaps or height. Baylor looked FASTER than Iowa. Getting up and down the court, in the half court, helping on defense. The only time Iowa looked faster was getting to loose balls- they do hustle, to their credit. But Iowa looked slow.
I told some friends at work this game was all about which Baylor team showed up. Unfortunately for Iowa, it was the good team.
