Because a lot of today's running backs are a bunch of pussies. Rawls getting KO'd because of a bruised shoulder? Give me a break. I know this is football, but come on. I lost a lot of respect I had for him today. If he can't play with something like that, than he doesn't deserve to be on the team. I could never imagine Marshawn sitting because of that. He was a warrior. His body was so trashed, but he still went out there and dropped the hammer year after year until his body finally said no more. Marshawn dove over the pile on a goal line score last year in San Fran. Only the elite backs are smart and tough enough to do that.
