Barkley's knee being down was not replayed. PSU did not necessarily snap the ball very quickly to make it so a replay wouldnt be possible. It is just too bad one of the headlines men, the extra back umpire, the umpire, the side judge, and the ref couldnt have seen that action. I would have thought the replay people would have seen it in live action as it was pretty apparent to fans in that end of the stadium and people watching the game.
