That never happened. He was never picked on constantly, he isn't slow, and those interceptions didn't just magically appear in his hands. He was in the right position in the called defense to make the play. That's by design, but the players have to be there to make it happen. That's why he played over guys like Crawford who were the ones busting coverage more often.
I wonder if you watched the season. In this day of offense first the DBs are always going to be at a disadvantage but he was one of the guys who busted coverage the least on the season.
Even against Washington the coverage wasn't bad for the most part. Penix was laser focused, we didn't pressure him, and their receivers were elite and made the catches on properly run routes. Our scheme was also more vanilla because of having a freshman or Crawford back there at all times who weren't ready or able to handle very complex coverages. Michigan had a better front, and better all around experienced DBs to really mix up on Penix for most the game.
