Generally, when you have a player who was one of the top 5 hitters in baseball in 2012, I think its really pointless to worry about giving him a two year contract.
Worst case scenario, the Rangers or Yankees sign him. Best case scenario, they sign him for 1/14, he's pissy about the short term deal, and hurts the clubhouse culture instead of providing the leadership that the team needs.
But then what? The team goes into 2014, and they have the same problem they have the last five years. They have no way of replacing his offensive production, or his PR impact. The three killer B's and the Ryans are either still developing in the minors, or struggling with the challenges of facing MLB pitching. The only scenarios where they don't re-sign him in 2014 are if he's completely done, and I don't think that will be the case here.
