Who knows what kind of shape Jackson is in. If he's been keeping in game shape then I'd say if he signs now he could be effective for the last game of the season and might be able to contribute in playoffs. It's not like they're a run first team anyway. Yeah, I know, game plan specific but methinks it's easier for this team to adjust towards the pass than towards the run. Look what happened when Lewis & Edelman went out plus the PHI game w/0 Gronkowski. McD tried to run more and we saw a WHOLE lot of Blount & Bolden 1 yard into the line runs. Get Edelman back & obviously the passing game "is" the running game....
