I don't buy into the 'if it wasn't peralta we wouldn't want him' argument. IMO this would be the exact guy they would target. He's having a down year so it keeps his price to acquire low, he's been very good for a number of years and our pitching system might think they can tweak him and get him back to being good again. They go for this type of guy somewhat frequently. But yea in this case they do know him so well that they know the personality/chemistry stuff is good.
To me, it would come down to if the Brewers pitching nerds think they know what's wrong with him this year and if they can get him back to what he was. Everyone knows the stats this year are poor, the idea is to get him back to what he was, if they can then of course we'd want him. I recall an article earlier in the year pointing out the differences in what the Mets are having him do. If our lab people look at his data and the conclusion is the Mets are idiots and we can fix him, and the cost is low then its worth a shot. Have to think his cost is much less than all the other names we've talked about around here, but yea if not the get the Ryan type instead. But the vibe seems to be they do not want to give up any of the upper tier prospects
Also, almost no one goes more than 5-6 innings anymore. Its just the reality.
