My guess is that Hart is the most likely to stay a Brewer. It's easy to overlook that he's good because several other players on the team are putting up better numbers than him. With Fielder, Hardy and Braun it's going to depend on a lot of things. For example, what players will the Brewers marketing department hang their hat on? For years, even when the team was doing bad people would go to see Gatner, Molitor or Yount. If Fielder's agent wasn't Boras, I think there's the chance he would have stuck with Milwaukee, because he seems a bit "shy." Braun on the other hand, unless he has a bad year or injury, is definitely not going to be with the Brewers after six years. He plays like he's a Yankee now.
