Jason Giambi
The Yankees signed him to a 7-year deal at age 31. His first season was MVP caliber, in 2002, yes. Last year he hit about .250, and this year now that he's off the juice his entire health is blown out of whack and he's got this tumor thing going on. He was hitting .221. Plus, he's had knee and back problems basically since they signed him. He DHed probably more than he played first last year, and I know he DHed every game in the playoffs. He's a defensive liability, an injury risk, and now a health risk. A $120 million dollar one at that. And we're stuck with him till he's 38 years old.
