Something else to consider is that it sure seems like a large portion of the booing is directed at, or caused by, Yost and his decision making. When Bill Hall is left in to face a RHP late in a game, and strikes out with guys on base, part of those boos have to be on Yost. It's doubtful that Durham, Counsell or somebody would be booed if they pinch hit and failed to deliver. Would Gagne have been booed as much if he wasn't constantly brought into high-leverage situations? Possibly not. What about when Ned fails to defensively replace Weeks late in a close game, and Weeks makes an error? Those boos are on Yost as much as anyone, in my book. He's alway putting players in a position to fail, and often times people are booing that as much as the failure itself.
