Right, but it's that determination that either dictates or precludes the application of Item 1 in the first place. Item 1 itself does not make that determination -- the catch process does. Control + 2 feet + time. Since 2015, the "time" part is "upright long enough". Before then, it was "any act common to the game."
Item 1 is indeed the guiding rule for a player who goes to ground in the act of catching a pass. But first, the catch process is the guiding rule that determines whether that player went to the ground in the act of catching the pass, or went the ground as a runner. If it's the former, Item 1 says the only way to meet the time element is by holding onto the ball after hitting the ground. If it's the latter, Item 1 doesn't enter into it, because the time requirement was already met.
Changing the standard from the football move to "upright long enough" effectively put Item 1 first. That's why nobody knows what a catch is anymore. Because if you put Item 1 first -- if you put "going to the ground" first -- then you have two problems. First, you have to justify why the catch itself becomes secondary to a player's body lean. Why now, instead of looking to see if he caught it, you're looking to see if he was upright long enough when he caught it. Second, you now have to define "upright long enough." Which, by the way, no one has even bothered to do, at least publicly. It would be high comedy.
Then I have to ask you why you think he wouldn't just say "in order to show he was in control of his balance," instead of using the words "in order for it to be a football move."
On whether or not Dez Bryant reaching for the goal line could have been considered a football act:
“Yeah, absolutely. We looked at that aspect of it and in order for it to be a football move, it’s got to be more obvious than that, reaching the ball out with both hands, extending it for the goal line. This is all part of in our view, all part of his momentum in going to the ground and he lost the ball when he hit the ground. That in our view made it incomplete and we feel like it’s a consistent application of the rule as it has been written over the last couple of years.”
The most logical explanation for what he said is that a football move establishes Dez as a runner. It fits with the idea that the catch process takes precedence over "going to the ground," because the football move is what completes the catch process. It fits with the casebook scenarios that say that the player doesn't have to survive the ground when an act common to the game showed he'd completed the catch process. It fits with the 2014 rule that said a catch was made if the player had control, two feet, and enough time to perform any act common to the game. Enough time to perform a football move.
If I take the opposite view, and say that the football move does
not establish Dez as a runner in 2014, then I'm scratching my head trying to figure out why he's even talking about a football move, and why he would go into detail describing what Dez would have had to do, in Blandino's words, "in order for it to be a football move." I'm trying to find some way to make sense of what he actually said, because it doesn't make sense if what I believe is true. I'm also wondering why he didn't just say, "The football move doesn't matter when the player is going to the ground."
