Brian Dawkins isn't exactly a "light" hitter, either
Being here in Giants-land, I get to see the Iggles/Jints twice a year. Dawk put Hilliard on the shelf for a few games two seasons ago, when Collins overthrew him on a crossing route.
Any safety worth his salt is gonna put a "don't tread on me" stamp on the head of a WR on a 20 yard crossing route. It's part of the game. Ballsy wideouts make the catch and take the hit---you're gonna get crashed anyway, so you might as well hold onto the ball like Branch did.
