It should be about the game. People get hurt, it's football. Some of these rules are ticky-tacky for sure. I understand the money aspect, as I mentioned, but flagging people for being too rough on one player is crap. It ruins the integrity of the game when first downs are handed out because a defender hit a QB a fraction of a second too late. The outcome of the game shouldn't be left solely in the official's hands, and this is essentially what they are doing. QBs already last longer than most other positions, and they are the best paid. There are no outlandish rules to protect RBs.
