Typically, yeah. But Fielder isn't built like a typical player. True but most of the guys who are built like Fielder last til age 32-35 or so before they just drop off a cliff... (Cecil was 33 with his last average or better season and Mo Vaughn was 34 with his) Prince is a better hitter and more agile than most guys with the same build that he should be able to last as long as them, if not longer. Heck Frank Thomas lasted til he was 40, but he had the DH to help him out. First of all, Thomas and Fielder are very different players in terms of how they were/are built. Secondly, both Vaughn and Fielder definitely benefited greatly from having the DH option open to them, especially once they got on the other side of 30. No, they weren't fulltime DH's, but they were able to spend at least a few dozen games in their post-30 season as a DH, an option Prince will not have with the Cubs. They're also two guys who didn't make it past ages 34 and 35, and that's with being able to play hundreds of games as a DH, so that's not a terribly good argument in favor of Fielder.
