"High hit" call

[WMUguy]

Good evening everyone,

I like reading this forum to get clarification on calls from the people that really do know what they're talking about. Fans love to argue, but you guys can pretty much put any debate to rest, so here's one for you.

This is a little over a week old, but I'm confused on the call. Northwestern at Vanderbilt, Sept. 4th. NU's QB rolls out on a designed run and gains about 5 yards before he's hit by the VU safety (looks to be a great clean hit to me). The call on the field is a personal foul "high hit". A lot of debate has centered on whether is was helmet to helmet, which to me is insignificant because it wasn't the call (plus it didn't look like it anyway). A couple of angles:

YouTube - Vanderbilt's Fullam penalized for high hit vs. Northwestern 9/4/10

(play starts at 8:17, call at 8:48) YouTube - Northwestern Wildcats vs. Vanderbilt Commodores - 9/4/10

Not defenseless, is there any justification for the call?
