I have never argued that Buchholz's contract was an overpay. His predictable long DL stints are very disruptive to the rotation and the team. It is hard to replace him for half the season with a pitcher of comparable quality. I would rather have a durable pitcher of somewhat lesser quality, as over the long haul of the season, I believe that reliability is very important. While I have never argued that Bucholz contract is an overpay, I don't think that it is such a bargain as to be a slam dunk to pick up his option, because of the cascading negative effect of his unreliability upon the remainder of the staff. Do WAR stats take into consideration those dynamics?
