Goes to the idea of completing the catch when going to the ground. The dispute here would be your 2-3 steps in possession. If that were so, then yes, down by contact. If not the steps/'football move' in possession, he must maintain control through the act of going to the ground. If that doesn't happen, it becomes a question of did the ball hit the ground. Here it did not thus interception. Had ball hit ground would have been incomplete.
I hear you, and I think this sequence of events falls into a case that the rule-book doesn't really consider.
With that said, before the review, the official said the AB was not down by contact, but rather because his forward progress was stopped.
So, some questions:
1. If the play is whistled/called dead because forward progress was stopped, is the "maintain possession through the catch" BS still come into play?
2. Can there be a change of possession AFTER a play is whistled/called dead because forward progress was stopped? If so, that would be a new one for me.
3. Back to the "maintain possession through the catch" BS... I thought that in the cases where the "maintain possession through the catch" comes into play in a "down by contact" scenario, the play is dead (because the player was down by contact with control of the ball at the instant he was down by contact) -- And the only question is whether or not it's a completed pass, or incomplete.
The idea that the opposing team can "intercept" the ball -- or gain possession in any way -- after a play was legally dead/over is beyond strange to me. I really doubt that was their intention, but I suspect they never considered this scenario and therefore the call is based on some on-the-fly interpretation and guesswork.
Do you think if the person who ended up with the ball ("intercepted") were a Steeler (another player on the offense), he could have advanced it? There's no way. The call would have been, correctly IMO, that the play was over one way or another when the receiver was down by contact with possession of the ball.
