Maybe. I have a hard time believing Spiller plays a significant role in their offense. He just doesn't to seem to be a every down kind of player. If they figured out a way to use him effectively and often that would be awesome, but I have a hard time with that. And if the other backs are the meat of this offense (which I believe) and one of them goes down, they cannot plug Spiller into that position. He is 180 degrees different from the others.
But this is all mental masturbation anyway, no GM in their right mind would offer a 1st for him in his last year.
