With regards to the Harrison vs. Goodell thing, I thought he has done a lot better trying to avoid the head to head hits. I think he realizes he can't win that one. IIRC, I don't think he had any fines last year. As for his comments to the press, I don't know if that is hurting his stock. Teams sign players who have done worse (Stallworth, Plax, Vick, etc).
If the Steelers can bring him back next year after all the teams passing on him, maybe we get the hungry beast wanting to prove himself all over again.
