And that was a catch by the 2014 rules, that Dez made a football move. They then changed it in 2015 and basically stated that catch is dictated by holding the ball long enough to be a runner after the second foot comes down, meaning it is TIME that dictated the catch.
So the issue of Dez was the NFL trying to flop around to justify the ruling they made then. But the rule was written so bad in 2015, they just admitted in 2018 that per the 2015 rules it was a catch. This was because the Jesse James play against the Patriots that the refs screwed the Steelers over with in 2017 and nobody was buying it.
It was a catch. I think the spirit of the rule was lost in translation by the refs. They do this from time to time. The way the actual rule was worded left for a lot of interpretation. The rule was most likely intended for WRs catching the ball as they were going to the ground, like diving catches or lunging catches. The refs then included all catches that resulted in the player going to the ground.
Another example of this lost in translation issue is putting your body weight on the QB when making a sack.
What you both aren't getting is the mechanics of the rules at the time. You had the general catch rule and then there were rule subsets that basically functioned as exceptions and
those rules took precedence over the general catch rule. The going to the ground rule is either a yes or no question and if yes, the ball can't touch the ground and come out. The official on the field didn't see the ball hit the ground because he was shielded from it, but the replay showed everything and it was ruled as such.
As for the 2015 rule
wording change, nothing about the rule itself changed. Time was always part of the elements of a catch so that was nothing new. You jump, land, and immediately get the ball poked out, there's not enough time to declare it a catch. That's always been the case. So despite whatever conspiracy trying to be created, nothing that happened from 2015 onward to the recent rule change was any kind of coverup. If you understand the rules as they were written (and the average football fan couldn't, which is why they re-worded it), you know it was the correct call at the time and all the way up to when they removed that subset rule taking precedence over the general catch rule. There was no "spirit of the law" being missed. It was always a yes/no determination. The field official missed what replay caught, which was that the ball hit the ground and came out of Dez' grip. By rule, that's a done deal and no catch. Dez needed to do all he could to secure the ball and take the 1st and Goal. Didn't happen.
