Dewayne Robertson
They were talking about his knee condition on Sirius the other day. Chances are that the Jets are going to cut him at some point this offseason, because teams aren't going to be willing to trade for him with this new information coming out and given his salary this coming season.
The bone on bone condition means that he has absolutely no cartlidge left in his knee, which is essentially what forced Curtis Martin to retire! It may not affect him so much right now, but it will definitely limit his ability in the future! You don't trade a draft pick or pay a high salary for a player with that much risk.
If the Jets cut him, then I think it would be worth it to take a look for a short term fix (1-2 seasons) but I wouldn't sign him to a long term deal worth much money!
