Then he stayed down giving himself up, then he got up and celebrated. Houston dude knew the rule. He had knelt earlier in the game. He screwed up but it's the rule. Like someone else said, at no point during that play did he give himself up. If he ran it out the results would have counted. You give yourself up by kneeling, not by throwing the ball.
Show me another pkay where that happened this year and I'll stand corrected.
