But he did not have full control. If the ball is in the air you could advance the ball forward by slapping it. Yes your arm is moving forward, yes the ball goes forward in the area of an area of a receiver, but no, you do not have control of the ball. And IMO Warner did not have control of the ball when his arm was going forward. And I really wanted the Cardinals to win the game.
Go look at the YouTube video and ask yourself honestly if the posters view that it was a pass (12 ft. with a little wobbling spiral) was not in fact a pass.
If it was Tom Brady it would have been ruled an incomplete pass.
