I disagree on the WRs would do a better job wrapping up. Maybe in some instances, just maybe, but not likely because they're not going to stop and think "oh, I can't put my hand down to protect my fall" which is what Megatron did. And they're not going to think "oh, I can't try to reach the ball across the goal line because I might lose it when I hit the ground". No, they're operating on instincts.
I would venture to say, but admit I can't prove it, that the catch rule has invalidated more legitimate catches by a wide margin than has validated or invalidated non-catches. And I think there is the rub for most reasonable people. I'd liken it to an organization or work-group that has a problem with 1 or a very limited set of employees. Rather than man-up and address the issue with the few, they institute a blanket policy that impacts the whole. The other thing I think that's in play is consolidation of power at the corporate level, ostensibly for "consistency", but there is a measure of self-importance and jobs that play into it as well.
