UCLA is playing at Autzen Stadium, so typical offensive line tactics and calls just won't work. One such call is the "look out" block, which many of us know and love. For those not in the know, the tactic is used when a lineman misses a block, typically to the quarterback's blind side. The error is followed by an expletive and the word "look out" to warn the quarterback he's about to be killed.
He got up and seemed to survive the blow, which is amazing. Not just because this was a vicious hit, but because this is Kevin Prince we're talking about. He's had just about every single injury a quarterback can have, yet somehow this massive hit didn't seem to leave him any worse for wear.
