They gave both Posada and Rivera multi-year deals at around the age Jeter is now. Those deals were quite rich, to the point that no other team would have come close to what the Yankees paid (well, maybe someone would have paid Mariano, but he never had any desire to hit the open market). It would not shock me to see him get a 4 year, 75-80 mill. contract. I expect his next contract negotiation (when he's 40 or 41) will be the one that is problematic to both sides. By then his offense and defense will have worn down to the point that as much as he might be an organizational icon, running him out there every day will harm both the player's legacy and the everyday product.
