The rule at the time:
"Item 1: Player Going to the Ground. If a player goes to the ground in the act of catching a pass (with or without contact by an opponent), he must maintain control of the ball throughout the process of contacting the ground, whether in the field of play or the end zone. If he loses control of the ball, and the ball touches the ground before he regains control, the pass is incomplete. If he regains control prior to the ball touching the ground, the pass is complete."
Process of contacting the ground.... completely vague, designed to let referees steal a catch when they feel like it.
One foot down, process partially complete.
Two feet down, process of contacting the ground complete!! It has been this way for all of pro football, and the NFL admitted they got it wrong years later.
If two feet down is not process complete, then running downfield 100 yards might not qualify either. And then losing control of the ball by a celebratory spike in the endzone would be losing control and thus incomplete in this bizarro world that spurs on endless arguments.
You see, the referees can bend the vague rules to confiscate a catch, when 2 feet down with possession is not enough. They did this to Dallas, and Mike McCarthy enabled them. Blandino wrote the language, and enforced it from New York. He is a clown, an incompetent thief.
Zero controversy, The referees and chatroom instigators have nothing to stand on. They will always be wrong. Dez caught that ball, 100%
