Come on, the safety launched a little late but he was going for a strip he wasn't trying to injure Barker. He mistimed it a little and I am sure there was some frustration at play but he clearly tries to make a play for the ball.
As for the subterfuge....yeah I don't think Michigan is going to lose a lot of sleep over whether or not AJ Barker is playing. He is having a nice year and he has certainly been our top receiver but he is not the kind of game changer that a Denard Robinson is. If Denard doesn't play it drastically changes what Michigan does, if Barker doesn't play we lose a valuable part of the receiving corps but it doesn't really change the offense.
