Argument from authority is fallacious. The rule is written in the English language. A language contains terms that correspond to concepts which have meaning. None of the words in the rule explicitly state that Item 1 "takes precedence" over "the main catch" rule. That is what is called post facto rationalization by an NFL spokesperson. He doesn't even use the right terminology. Item 1 would merely come into play if c) can be justifiably questioned, which can only occur if the player is unable (because he is in no position to enable himself to execute a move "common to the game"): "Note 1: It is not necessary that he commit such an act, provided that he maintains control of the ball long enough to do so". Now that I think about it even more, this renders all of "going to the ground" irrelevant because it is simply a judgement call that is disputable as to whether Dez couldn't do at least one of those things in c) referenced as an example after doing a) and b), especially an attempt to pitch the ball since he clearly had two hands on it and had control enough to move the ball to grasp it in his forearm and attempt a reach with it after both feet touched the ground.
The term robbed in the colloquial football context has the connotation of believing that something was taken from your team that they rightfully possess. Conspiracy implies a nefarious intention by two or more league officials to willfully remove that possession. Learn terminology.
Yes, I do. Johnson pinned the ball with one hand with his hand on top of the ball and its bottom on the ground clear for the world to see as he came down on his butt using it to brace his fall. After that the ball was lifted slightly in the air when he tries to grip it with his hand which he fails to do. Watch the video.
No it's not "clear as day". And like I said, the rule states, "If he loses control of the ball, and the ball touches the ground before he regains control, the pass is incomplete." Read the sentence over and over gain and pay attention to what the language explicitly states about sequence. The first phrase precedes the second phrase and this positioning also implies a prior sequence in time which means he has to have lost the control of the ball before it hits the ground. The "before he regains control" is redundant, but nevertheless it emphasizes the situation even more. But that doesn't apply to Dez when he makes the reach because he had control well before that point. That only applies to when the ball is jarred loose due to the force of ground knocking his arm and the ball upwards out of the full possession of his arm into a slight bobble which he catches anyway before it can hit the ground.
He did execute. He just didn't execute to a undefined standard of extent that you presume to apply, which is irrelevant anyway because all the rule requires is that the receiver must have enough control to enable him to execute such a move.
