re: I'm hoping a Super Bowl will one day be decided by a controversial

I'll add this to my opening argument.

Here's Cary Williams on why he horse collared Darren Sproles near the end of last night's game:

"He broke contain. I'm the safety valve there. I didn't want to dive, because if he steps out of my tackle, it's six points. I just wanted to get the man down, just give our defense a chance to get on the field and make a stop."

So, for the sake of consistency, why wasn't Sproles granted the yardage he would have gained without the penalty? Why should Williams be allowed the discretion of a 15 yard penalty versus a potential long gain but that privilege is denied to a defensive back? Why is it not even worse when Williams makes that decision when HIS penalty can physically hurt a player?
