I don't think Penn State let up. I don't know who coaches their D-backs, but they were out of position, missed tackles and otherwise committed PI. Michigan grabbed the momentum and got back in the game. When Penn State scored to make it 28, I started to relax a bit, but Michigan came back again. I was on pins and needles. They're doesn't seem to be a middle ground when these teams play. It's either a blow out one way or the other, or a nail biter coming down to the last play of the game. Big Ten has become more competitive over the past couple of years which is great to see.
