The problem is that you really can't remove rules, or aspects/components of rules now. They have to be more specific rather than less, and the more specific they become, the more people will be pissed off about situations like what happened or their general inability to know what the hell a catch is anymore.
In this case I don't know what tweak to the rule could be implemented. Seems like "ball hitting ground then moving around in receiver's hands equals no dice" is pretty simple, and for the most part reasonable.
I do not share your assessment that you cant remove rules, or aspects/components of rules. I understand that some will agree with the rule as it stands. I saw that as a clear catch and touchdown, and do not feel that the rule makes sense. I feel that there needs to be a re-working of that rule to somehow allow that type of play to stand. That's all. Not interested in getting into a debate about it. Just stating my POV.
I went back and read my previous post, and perhaps I worded it it more as a statement of fact, so I will edit it here:
When judging by the specific NFL rule, it was not a catch. By my own personal eyeball test and common-sense, it was a catch and touchdown.
I wish they could, and would, fairly and reasonably change the rules to have that be a catch. I know some will disagree that is possible, and some will argue it isn't even needed. That's cool, and I respect that.
