Think about that again.
Bosa lines up as close as you can get to being offsides, jumps the snap, uses his hands well and still had trouble turning the corner consistently at a reasonable depth.
Not good.
Then there were the times when he just, like, fell down during plays. My old defensive line coach Rod Marinelli hated to turn on the film and see us on the ground. Usually it was a sign of a guy with either bad balance, bad technique or some combination of both. With Bosa it usually wasn't technique, so what's left? Let me tell you, a pass rusher with poor balance is going to have a hell of a time trying to win against offensive lineman in the NFL.
