well, a fella by the name of nick saban agrees with my assessment...
"I don't think it was Jalen Milroe's, necessarily, all his fault," Saban said. "The first play of the game, we're supposed to be sliding that way, tackle slides, guard doesn't, quarterback gets blown up. Third play of the game, they pressured us and we didn't pass off the game inside. Once your quarterback starts getting affected a little bit, even though it's not necessarily his fault completely, it's tough to play. We got to the point in the game where we didn't have a lot of confidence in being able to throw the ball. Not because of our skill guys but our inability to protect."
UW's o-line is surprisingly young (3 juniors, 1 sophomore, and 1 RS freshman), but they had a great year. As someone else mentioned, they won the Joe Moore Award for the Most Outstanding Offensive Line Unit in College Football. While they certainly haven't seen a line as physical as Michigan's, I'm hoping they'll be better prepared than Alabama was.
And, of course, their ace-in-the-hole is Penix, who has a knack for avoiding sacks. Michigan's secondary doesn't usually need to cover guys very long. Just a few seconds and then the pressure usually gets there.
