This is so needless. Take of your glasses and watch the play. The ball is out of his possession when he’s halfway through what everyone knows to visually be the process of a catch by watching so much football.
Seriously. I don’t care what portion of the catch you adjudge it to be he’s clearly somewhere in the middle of the process of surviving the ground. He was still in full motion from the initial impact. That motion is the process. You aren’t done surviving the ground if you are still clearly in the early / mid stages of your fall/tumble
imagine how inhuman it would look, for example, if at the point the ball was being held by both players the bills receiver stood up. As he was on his back while going head over heels. He was CLEARLY still in process of surviving the ground
