I would be surprised if we didn't sign Jamal Lewis, because he's a perfect fit for this team. A better fit than Edge or Alexander IMO.
First, there's the money issue. G & G have stated that they will not go after a big-time FA RB that would command 7M a year. Well, Lewis' price is probably around $4M plus incentives, so why would G & G's comments include Lewis? They signed Okeafor on a front-loaded 5 year - $25M deal. Why not sign Lewis to a lesser deal in an off-season where they have more money to spend?
Second, signing SA or EJ would mean a feature RB getting all the carries, but Lewis at a lesser price wouldn't "force" Green to keep him on the field at all costs, leaving Green's draft choice JJ in the mix. JJ and LEwis would make a nice combo.
Third, as alredy stated, Lewis fits the description of FAs that Green likes. Lewis has something to prove, because he didn't put up the expected production last season. I don't think that means Lewis is done. I heard an interview on sporting news radio with one of his teammates in Baltimore (Can't remember, but I think that it was Heap), who said that Lewis had been running at 90% all year, because he didn't want to risk an injury. The rest of the team knew this and could understand this, because if we management weren't willing to commit to a long-term deal, then Jamal had to protect himself.
Finally, Lewis would be a huge upgrade over Shipp and a nice improvement to the team.
