That's a beautiful hit there, and I can't see why you'd call it a blindside hit if it's from the front. As for the Alabama thing, I really feel like they're calling petty things just for the sake of calling them. I feel like it could go either way for a late hit, but to send him to the showers for that, 100% no.
One thing that I've noticed is that now that a receiver leaping to make a catch is a defenseless player, how is the corner supposed to legally defend the play? Is he supposed to just let the receiver catch the ball and tackle him cleanly when he lands?
I think Mike Pereira says it best-nobody really knows what targeting is and isn't. I really hope the NCAA will change/clear this up next season.
