Taylor Brayton Fined $15K For Out of Bounds Cheap Shot

How is it that Taylor Brayton only got fined $15K for this vicious cheapshot on the Falcons gunner, yet James Harrison was set back $75K for his hardnosed hit on Mohamed Massaquoi. I'm fine with the NFL taking a tougher stance on player safety, they just gotta be consistent. And this minimal fine for a play that you should never see in a professional game is ridiculously outta wack. Or at the very least make a rule that if a gunner runs over the white line he's fair game for anyone on the bench.
