ams could do something if they find a QB, but the move might set them back a little.
colts could be one of those teams where a back is worth it, luck and gurley would have scared the crap out of Ds
one last note, marshawn lynch is a perfect example of what you described. he was good but not great in buffalo, but he was never on a good offense there. in seattle i doubt they win the superbowl without him, and should have given it to him for a second!
he was a first round back that had a great career, though he did switch teams. had he stayed out of trouble the bills may have have kept him
