I guess when you look at it that way, it is a good sign that the Cardinals aren't getting every, single, ticky-tack call go against them like it has in the past. I know I was holding my breath when the punt was blocked. My instinct was that it was going to be nullified and Dallas would have a first down out of it somehow.
As far as the hand on the facemask and hit to the head, too much interpretation is going on in today's NFL. I completely support protecting these guys but too many fumbles, drops, etc. are being over analyzed, it seems, at the expense of common sense.
It certainly supports the idea that if human error is going to be part of the equation, then let it be part of the equation. I don't think anyone wants the game called down to the frame like it is now and the penalties that they are often calling seem so arbitrary and beyond the spirit of the rule.
I think it's clear that all of the over protection of players and QB's in particular isn't really that effective. If Tom Brady is lost for at least a year then what has all of this protection really accomplished? It seems like plays that should be called dirty are allowed and plays that are flagged are incidental. It's very frustrating as a fan, that's for sure.
