I think I get what jlohm1 is saying about Bruce. Its' not that the guy is without talent, but there have been countless players at the major league level with the same potential who never lived up to the hype. I remember hearing the same kind of talk about Austin Kearns. Bruce is special in the sense that he has the tools to be very successful, but he hasn't fully lived up to that potential. He needs to find a level consistency throughout the season. So it's hard to say that he is truly a special player just yet, really good though. Definitely not a star.
Bruce's HR and RBI totals have went up each of the last four seasons, so he is getting better in those areas. However, his batting average needs to improve. We have seen a drastic variance in that category from year-to-year. At the plate Bruce looks a lot like Ryan Ludwick from 2007-2010, and nobody is saying that he is special or a star for that matter. That said, where Bruce excels is with his defense, it sets him apart from players like Ludwick.
As far as trading Bruce when he was in AAA. I can't answer that, depends on who I get in return. Nobody is untradable.
