The Pirates should not be buyers, the Brewers, Cardinals and Reds should be without a doubt. You don't get that many shots at the playoffs and all of them are in solid position to make it and once you make it you don't have to be the best team to win it all. To be honest if the Brewers were sellers it would be just about the dumbest move I've seen in baseball, they define the type of team that has to go for it now.
