You have made some good points. I am still curious whether Pig is left handed or not. I am not sure this is determinative especially with him closing in on the sideline but it is an interesting question.
You continue to conflate what Pig actually said with your own analysis. And as quickly as the play happened I can understand Pig not having the perspective the visual evidence brings.
You have at least made an effort to address the changing of the hands. I see what happened differently and believe he consciously switched hands.
One's elbows would be extended in switching hands to prepare for a dive.
If you understand physics even slightly, and you watch, you can see the moment when his force is reapplied from the ball into air. His right hand goes almost to his left elbow.
At that exact same time you see his left hand start to move to the right, and you see the trajectory of the base of the ball move to the right, but the top of the ball moves left. This shows someone without control trying to re-grab the ball and the ball moving away from their grasp.
Aldon is right handed, and the first thing he did when he hit the ground was look for the ball, not celebrate what may have been the winning touchdown. Because, as he said, I knew I fumbled it early, and was trying to jump on it.
