"I would put my life savings on Hart not having anywhere near these numbers at the 2011 deadline, granted, he seems like a guy that will turn it on as hard as possible in a contract year." Even if the Brewers trade Hart right now no team would expect him to continue what he's been doing. They are going to make some kind of projection for his expected performance, which is going to fall somewhere between his current numbers and his career numbers. Using Hart's updated ZiPS projection: Current: .290 / .348 / .562 Projection: .274 / .333 / .493 Career: .276 / .329 / .483 The way I see it, the notion of selling high is based mostly on the falacy that teams pay proportional to a player's current production. The Brewers could trade Hart today but if he continues to beat his 2010 season projection, the Brewers would have actually sold low.
