James Harrison has a legacy with the Steelers. He and Troy P. are two of the best modern great Steelers on defense, IMO. I think there is a lot of sour grapes right now..."how could one of us go to the Patriots on the eve of the playoffs" type thoughts.
Harrison is 39, how much more time will a 3-4 LB that age have? If he is still that good, Harrison would be starting for Pitt, or at least get more playing time. He'll retire a Steeler soon enough and doubt he'll be that effective with NE. Belichick is just being a prick.
