So you are saying you will blow this dead while the player is still in the air because the ball is dead before he even comes down?? No way.
This ball is live until he comes down. At that point he is in the EZ with a live ball that then becomes dead because of the TD.

Possession requires touching the ground so you have to make sure he controls the ball until he has both feet down. Then you can rule on progress.
