It's hard to feel positive about McBeane fixing the O when they seem intent on bringing back one of the worst RBs in the league this year. The only way this makes sense is if Shady were to restructure his deal, but from what I have seen from Shady in his time here I don't expect that to happen, we'll see.
IMO, Shady's elusive running style, predicated on agility and quickness, won't allow him to be one of those rare RBs that run well into their 30's.
