Uhh. He was referring to the guy CATCHING the ball as waving his hand at the last second.
Yeah, I see where I misread his post. However, he's still not understanding the rules.
There is no such thing as a "late" fair catch signal. Unless, of course, you wave your hands around after the ball has bounced off of you or the ground. But as long as the ball is still in the air, you can call a fair catch.
Interference is interference. Chad's acting as if OM was getting close because he thought it was a live catch and that he could smear the shit out of him. This presumes that you can get close to the guy when he hasn't signaled for a fair catch, but that you can't get as close to him if he has signaled for a fair catch.
That's not the case.
If you're too close to him before he catches the ball, then you're too close. Regardless of whether he's called for a fair catch, you can't be all up in his shit before he has a chance to catch the ball.
Remember what players did when the halo rule was around? If they got there early, then they broke down in front of the player two yards away and waited for the catch. Chad keeps asking, "Well what was OM supposed to do?" That's basically what he was supposed to do: break down in front of the guy, not run up as close as possible to him before the ball is caught.
With this whole "judgment call" thing, it's difficult for a player to know where exactly he needs to break down. But, based upon the fact that the rule doesn't allow them to sprint up to/past receiver and come very close to the receiver, it's pretty clear that a kicking team player needs to keep his distance to some degree and wait for the ball to be caught.
