What bargaining chips do we really have? Ronnie Brown is really the only marquee, and I'm using that term loosely, player we have that's under 27.
The one player I think that we might be able to use as a bargaining chip that realistically could get us something in return is Samson Satele. He's young, athletic, and has proven durable during his first two seasons, but when you have to face Wilfork, Jenkins, and Stroud twice a year, with Casey Hampton, Jamal Williams, and Albert Haynesworth (if he's re-signed) on the schedule next season - all of which are big guys which Samson struggles with, I think a move could be made.
A bigger C is a must for the Dolphins going into next season in my opinion whether it's Jason Brown the RFA from the Ravens, Max Unger, Antoine Caldwell, or Jonathan Luigs, Satele is more a liability than a strength at the pivot given his skill-set. A team like Indianapolis or Minnesota that run a lot of stretch plays and have aging centers might be a target.
