I thought he had possession when his knee hit the ground and that he lost the ball after that.....but I can't swear to it
because I must admit I've been imbibing in fine spirits.
The operative term being "with possession" when receiving a catch and falling down a player is not "with possession" until they finish falling down and still holding onto the ball. If he had two steps and THEN started falling (like from getting hit) it would have been a completion, but he was falling before the ball touched him that meant the fall rule applied, and the fall rule says you have to keep holding onto the ball until you fall.
Wether the call was right or not doesn't bother me. I consider it a payback for the lousy call on Alstott's TD in the first game. I guess it all evens up. Go Skins!
