Only way I trade Revis is if A: I'm getting a solid QB in return. I don't think you trade Revis for an upside guy. Also, B: The team that the Jets trade with takes Sanchez off the Jets hands.
You get a solid qb/prospect and they get the best cb in the league and they take Sanchez's contract... then go for it.
But in reality this wont happen, so don't trade Revis. Especially now that Cromartie has found his inner Revis. This tandem may reach its full potential next season and paired with Landry... I want to see that. This D has the potential to be the best they have had yet. After finally getting some guys that are finding ways to the QB.
