I don't mind the rule at all. I despise this interpretation of it.
The process of a catch ends when possession is established by normal means. If you go to the ground in the process, that means possession was not established before going to the ground. IE he caught it in the air and hit the ground, losing the ball. I like that interpretation.
If you make a catch, take 3 steps get a knee down and then hit the ground or roll over and start to get up it is no longer the process of the catch. It is after and should be a TD.
Both Finley's and Johnson's catchs it was after the process of making the catch when they went to the ground. Johnson was even starting to get up from hitting the ground when he lost it.
It is a terrible interpretation of a good rule. The NFL is covering for the Refs blowing it by explaining it away. Just like the tuck rule. The refs blew it and the NFL backed them by saying that is how you are suppose to interpret it.
I want to go out like my Grandpa did. Peacefully in his sleep.
Not screaming in terror like his passengers.
