Syracuse has told their runners including the qb to leap into defenders using the knee to inflict the maximum blow. No way this was an attempt to leapfrog. I'm surprised that's legal but apparently it is. It's dangerous not only to the defender but also to the runner. In my view refs ought to make a judgement call. If there is a reasonable chance that a defender can be leapfrogged fin but the crap we saw from Syracuse? Fifteen yard penalty.
