@OmerV you can read percy's post above and then I will show you here where the twisting happens (not that you need it).
You seem like someone who's honestly trying to understand this. Before moving on to the two disagreements, I hope I've helped you with the football move part of it.
There can be no disagreeing about what constitutes a player going to the ground in the act of catching a pass, because it's not open to interpretation. Your opinion and my opinion don't matter. A player who has not established himself as a runner, and who goes to the ground, goes to the ground in the act of catching a pass. Rules that apply to receivers (like Item 1) apply to him. A player who has established himself as a runner, and who goes to the ground, goes to the ground as a runner. Rules that apply to runners apply to him. Item 1 does not apply to runners.
So far, so good.
To your other point, since 2015, a receiver judged not to be upright long enough cannot go to the ground as a runner.
Here it is:
False.
If a player is not "upright long enough" to "demonstrate that he is clearly a runner (2015 GTG rule)" then he is simply going to the ground the same as 2014's rule. All it means is he didn't complete the 3-part process before landing on the ground. How does one "demonstrate" they are clearly a runner? Via time or football moves. As Ive said before, since contact is irrelevant in the GTG rule, a DB can instantly bear hug a WR so he can't make any football moves before they both go to the ground and the WR loses the ball after hitting the ground. How would you determine this WR is clearly a runner? Via judgment of time. And as such, this player would go to the ground as a runner in either 2014 or 2015 whether the official deemed he "maintains control of the ball long enough" in 2014 or "has clearly become a runner" in 2015.
However, prior to 2015, there was no such rule.
It's not a rule. It's further clarifying what the 2014 rules said due to the outcry of "the rule is too hard to understand." See above.
If you've been trying to tie up the loose ends, and you don't know what to do when you get to Blandino saying the reach needed to be more obvious, well, now you know. He had to address the reach. Because at that time, you could complete the catch process and become a runner, even while falling.
Again,
false.
This is where the case plays come into play because these were held up as examples of a receiver becoming a runner as he was falling to the ground. Here is the one that appears in the 2014
AND 2015 Rulebook/Casebook
A.R. 8.12 GOING TO THE GROUND—COMPLETE PASS
First-and-10-on B25. A1 throws a pass to A2 who controls the ball and gets one foot down before he is contacted
by B1. He goes to the ground as a result of the contact, gets his second foot down, and with the ball in his right
arm, he braces himself at the three-yard line with his left hand and simultaneously lunges forward toward the
goal line. When he lands in the end zone, the ball comes out.
Ruling: Touchdown Team A. Kickoff A35. The pass is complete. When the receiver hits the ground in the end
zone, it is the result of lunging forward after bracing himself at the three-yard line and is not part of the process of
the catch. Since the ball crossed the goal line, it is a touchdown. If the ball is short of the goal line, it is a catch,
and A2 is down by contact.
Note the wording that says that the lunge the receiver executes is not part of the process of the catch (3-part rule). It doesn't say he completed part c of the 3-part rule via an act common to the game (which would be way easier), it says lunging is NOT part of the catch process. So if you can't say it was a football move, then it was TIME just like noted above. This case play appears in the 2014
AND 2015 Rulebook/Casebook. In 2014, you'd say he had "long enough" to do a football move, and in 2015 you'd judge that he "clearly became a runner" because of TIME.
No one who defends the overturn has ever been able to answer this question: If the football move didn't matter, why did he say he looked for a football move?
I answered it in
this post when correcting your wingman concerning the case plays. Blandino looked for a football move because it would have proved Dez had the ball "long enough" per the 2014 rules as well as interrupting his fall visually. That's why Blandino also talked about Dez' momentum in going to the ground and that there was nothing demonstrative to prove he wasn't always falling. Also, note in this case play that the receiver has the ball in one hand before lunging. Doesn't say he caught it with one hand, right? If we reasonably assume he caught it with 2 hands, then he "switched hands" in your words claiming a football move (he really just takes one hand off). Does the Case Play say that's what made this a catch or was it the brace and lunge? That's more evidence that these bajillion football moves people say Dez did on the way to the ground don't mean anything when GTG is slapped on you. A properly executed lunge does, which still is NOT part of the catch process so that act is different anyway. This is why Pereira can say that GTG trumps the 3-part process in tying Jesse James' catch with Dez'
That's the loose end. Understanding the rule change and why it happened ties up that loose end.
Which as I just explained, isn't a change at all. Same rule now as then which is why Pereira directly linked the Jesse James play to Dez' play in saying that GTG trumps the 3-part process. If they were under different systems of judgment, he couldn't say that so emphatically and I've yet to see anyone fact check him openly. Surely the Dallas press would have been all over that one.
The role that the 2015 rule change plays in all of this can't be overemphasized. The football move was completely eliminated from the rule book as a direct result of the overturn of Dez's catch, making it impossible to question an official's decree that a player was "going to the ground." And because there was no longer any football move to look for, the replay official's job of explaining his decisions became much easier and the field official's job of determining what a catch was became much harder. The rule change effectively meant the field official no longer had a say in this kind of play.
This is the closing
falsehood.
If there was "no longer any football move to look for" then how is a receiver deemed to "clearly become a runner" by an official in 2015? On a whim, or the same way as always: via TIME or a football move. This is the question I have asked you directly 4 times without an answer from you. Maybe if OmerV asks you it'll make a difference because at this point I'm not sure if it's now just an ego thing.
The dividing line is simple for GTG. If you don't want to have GTG slapped on you, then prove you are a runner via time or an act that says you aren't going to the ground. The GTG rule is a substitute for a receiver who has not completed the 3-part process, whether a receiver straight line dives and only has control of the ball but not 2 feet down or time for a football move or like Dez and the caseplay where there's control, 2 feet, but not time for a football move that proves you're a runner. The lunge saved the caseplay player, but Dez did not execute one as stated by all the major rules players both on game day and beyond. Analyzing backwards from there doesn't change that fact.
