I think y'all are missing the most important thing. AR 5-1-3-I scenario (b) does not say that he goes to the ground. So, with this interpretation, if he gets contacted by an opponent and he lands in the field of play - on his feet, and completes the catch - the ball is dead and he gets progress to the point that he first held/controlled the ball = TD.
But, 5-1-3-II tells us that, if he is NOT contacted by an opponent, then he gets progress to the point where he completes the catch if he is going to the ground while making the catch; otherwise, the ball remains alive and in play if he lands on his feet, completes the catch, and does not go to the ground with his actual effort to complete the catch.
This is a significant change in the interpretation of progress. Before, if he was contacted by an opponent, but remained on his feet after completing the catch in the field of play (not so held that his progress was stopped), the ball remained alive, and progress was determined by where the ball was subsequently declared dead. For 2022, he gets a TD.
That's how I read it. If not sooner, we'll get Shaw to explain this during a meeting in which he'll be participating on July 23. If somebody else gets something sooner, please share.
