Wrong. You just described precisely why he didn't catch it. The ball can touch the ground but you have to maintain possession of the ball throughout. The ball actually leaves both his hands before he re-possesses it. As I said before, dead in the water by rule. Now you get it. And yes, those rules kick in for catches, otherwise, why are they even there if the main rule can apply to every situation? It can't which is why those other scenarios have to be described and enforced accordingly. Not understanding this is why people get fooled and immediately jump to conspiracy when it's really about knowing the mechanics of the rules. I told ya so before.
And of course the videos are not the same situations. Those videos were solely to demonstrate a proper lunge, which would have gotten Dez out of the going to the ground rule which by your own recounting makes his catch no good.
No, not wrong. a), b), and c) all visually apply to Dez. You want to assert that Item 1 overrides them. Nowhere does any part of the rule state anything about the latter overriding the former. Even if granted that it does, the item is there to determine if there is a doubt about possession established via player control through the act. It says nothing about the ball touching the ground being the cause for loss of control. It says if the player regains control
before he touches the ground despite the ball touching the ground the pass is still
complete. And if the ball supposedly leaves both his hands before he re-possesses it, that means he had possession, and therefore it can't be incomplete (it would be considered a fumble before the repossession, and the ground cannot cause a fumble even when a player is merely touched while going to ground). The point is to establish possession via control of the ball. The concept of football moves is there to reinforce the establishment of control which defines possession of the ball.
Everyone and their mother who has been watching football for years knows Dez caught it by every meaning of the term. The only way Dez didn't catch it is an interpretive dance around a rule that allowed it to be overturned, completely defeating the spirit of the rule.
