So, I've watched it again, and again. I can't figure out what the personal foul was for.
It was sort of a cheap shot, but the official comes out and says, "After the play. Personal foul. Unnecessary roughness."
But go back and watch it -- Lewan CLEARLY hits the guy BEFORE the whistle. You can argue that he should have been looking forward and left (to see that the play was basically over), but aren't these guys coached from day one of Pee-Wee football to "play until you hear the whistle?" Normally we celebrate O-Linemen that get down field and finish with a pancake block.
For something that ended up being one of the (in my mind) critical momentum changers, this is just a shame. I was blaming the entire game on him (the PF and the two false starts), but now I have to reconsider.
