I just saw the hit for myself. The only thing that saved #66 AUSTIN KING is that he wasn't behind Vickerson when he hit him. But he wasn't infront of him either.
At the snap of the ball, Vickerson was engaged by the RG and the center and driven left, which was where the running backs were going. After following the RBs to the left side, the center disengaged leaving the RG on Vickerson, but never took his attention off Vickerson. When Vickerson recognized the bootleg had gone right (one second later), he disengaged the RG and turned right. And it was at this moment that the center (#66 Austin King) looked him right in face, then ducked his head and exploded into Kevin Vickerson's left knee from the side.
Alex Gibbs strikes again. Like Bob Griese said, King didn't have to do that. The play was well beyond them. It may be "legal", but it sure ain't right. It was cheap. Remember, Warren Sapp's hit on Chad Clifton was "legal". But it was a total cheap shot away from a play. Clifton spent a month in the hospital.
Even though it looked like he was waiting for Vickerson to come back to him so he could chop him, I don't think the Austin King was necessarily being low class or overly malicious here like Sapp was. I just believe that he's been coached that way by Alex Gibbs. It may be "just football", but only teams like Denver and Atlanta play it that way.
Honestly, when was the last time you saw one of our lineman pull a stunt like this??
