Even if (horror of horrors) he did retire today, I wouldn't blame Beane. Others have rightly said that many players have injury histories, and the only way to get a big name like that is to outbid everyone else. You just have to pull the trigger and hope you're not unlucky with them. Hopefully we get enough games out of him that it's worth it. If he is going to miss some games this season I hope we have him for the run in, because that looks on paper like the really tough part of the schedule and obviously leads into the playoffs.
