Why are you always so against the Brewers acquiring guys who used to play here? Its not exactly an apples-to-apples comparison, but Sabathia was 6-8 with an ERA near 4 when the Brewers traded for him. I imagine that smart teams look at more than just the last 4 months of results when trading for a veteran pitcher, and Peralta has a very solid history. If he were pitching better, it is likely the Mets would be closer to contending, and he wouldn't even be available. If the Brewers determine that he's the best fit of what is available for veteran starting pitching, I wouldn't take issue with it, former Brewer or not.
