So it's just assumed that Vitters has the highest upside? How high is that upside now? I know people raved about his raw abilities and how even though he might not walk a lot he might put together one of those rare high average, high power, low walk careers. But we know he's not going to be Vladdy. He's not even going to be Aramis. What is his upside, and is there really nobody else in the system that's higher? Is he a worse hitting Adrian Beltre without the defense? There's no question he has to stick at 3B to be considered to have any chance at upside, right? I'd disagree that Vitters' upside is the highest in the system, but I'd put him in the top 5 for that (behind guys like Lake and Archer). Vitters' stock is down, but he was very young for AA and the Cubs' handling of him has me wondering whether we'd be talking about him as the top prospect in the system had the Cubs left him in the FSL. Moreover, while his plate discipline leaves something to be desired, he's always had a good eye...but an impatient trigger to go with that eye. It's also worth remembering that he is the best power hitting prospect in this system by a good margin. His upside is probably somewhere in the Aramis Ramirez range, maybe a tick below that, depending on whether he becomes more selective. If he moves to 1B or the OF, his upside diminishes. I think his athleticism should be good enough to make him an above average defender at those positions, plus his bat should be roughly league average at those spots.
