Nor will he ever be.
What makes you think a 32 year old outfielder who is getting slower, losing range, and is suffering nagging injuries to his shoulder and foot will somewhat get better.
Face the facts. Damon posted a 25 FRAR rating his second year in Boston (career high) last year, it lurched to 14, this year it's slipped all they way to one. His .350 OBP is good, but is it superstar money? Not even close.
