Basically, that some of these kids have a shocking lack of self awareness. Styles was probably going to be ND's 5th best CB this year at best. I can't imagine he'd be better than that at tOSU as they are usually stacked in the secondary.
If he wanted to play he should have transferred to the University of Ohio in the MAC. I don't mean that as sour grapes or to knock the kid, but the guy's not played CB since HS. If the goal is to play and develop he wasn't wrong to leave ND, but picking tOSU isn't a better option.
