i dont know Dew, i think posada is a real gamer and leads from the front with his clutch hitting and solid catching. personally i think posada is worth keeping, i have no idea what he is demanding for his services but one could build a solid team around him.
rivera is an old man, the rockies ought to step up and pay for his services, he would be devastating in the national league for a year or two. now bernie williams might still be able to make a comeback and giambi is worth every dollar the yankees can throw at him to sit on the bench.
