It does look like the knee was down first. But good that the Godly Chip threw the flag like an idiot.
If I'm honestly pin-pointing the play that really let this game get out of hand, I would say the Hester Fumble.
Woo, time to celebrate! I was down 1/4 of a second before I fumbled the ball! Last year the replay challenge wouldn't have happened.
When you throw the flag wen you aren't allow, Thats a 15 yard unsportsmanlike penalty. Not a time-out.
I think back to that Picture Mongo had in things to watch, "I don't know what happened, but it's against the Bears"
