FSU should put this hit on a teaching tape. Joyner didn't lead with his head, didn't target the head, and did not launch in lieu of simply tackling. Joyner does go airborne, but has to because he is 5'8 and the opposing receiver is jumping as well.
As Jimbo Fisher said after the game, plays like this should be reviewable. They happen too fast to be called on the field with any sort of consistency and accuracy.
FSU's athletes are simply too fast for the human eye.
