Right now, there are ten right fielders that have a higher WAR than Drew, and most of them cost less. Sure, he's above average defensively and offensively, but when he sits 20% of every season, that hurts his value considerably. He's pretty much untradeable right now, so the Sox are just going to have to deal with it until he's gone at the end of 2011. But then again, he's been the only consistent piece in this outfield this year, and he's the sort of player who exceeds expectations in contract years, so he's worth holding onto, maybe he'll yield a draft pick.
Beckett was signed for a 4/68 year deal back in April. Dice-k has two more years.
