Nwaneri signed a five-year extension reportedly worth $24 million in 2010. He, along with center Brad Meester and guard Will Rackley, has struggled this season, although Nwaneri and Rackley are dealing with knee injuries. Jones-Drew is in the final year of his contract and is unlikely to be re-signed.

Tight end Marcedes Lewis, who has played only two snaps this season because of a calf injury, also could be a target. Lewis signed a five-year contract worth $35 million ($17 million guaranteed) in 2011.

Not one of those players, all of whom are 28 or older, is in the team’s long-term plans. If Caldwell can get anything substantive for them, it’s almost a no-brainer. It’s not going to be easy to watch the product on the field, but everything now is about 2014 and 2015.

He's not that expensive, and none of the money left on his deal is guaranteed.

He's a LT though. So you'd have to switch Martin back to the right side, presumably.

I'd rather stick Nate Garner in at either RT or RG.

Clabo is not what I expected at RT
