Petit was indeed terrible last year, but at 22 I think it's too early to call him a bust. John Maine is a good example of a pitcher who looked promising initially (maybe never as highly regarded as Petit, but somebody the Orioles were hoping would pan out), saw his stock plummet over a season, then rebounded nicely. And sometimes pitchers need more time than fans are willing to give them. Adam Wainwright was a very highly regarded prospect in the Braves system a few years ago, to the point that somebody making a similar list to this one on John Sickels' blog last month listed him as a bust even though his current team would not have won a World Series without him. I wouldn't be surprised if Escobar (naturally assuming no injuries) finally gets a full year in the majors this year with the Nats. He may even do something with it. But I do remember some site projecting him as a "future All-Star," and that didn't quite work out. I thought the luster was off by the time of the trade. He'd been doing fine in AAA early in 01, then came up for two weeks when Payton got hurt and promptly forgot how to hit, then didn't hit much when he returned to Norfolk. I was OK with selling while there was still value. My impression, from looking at the Baseball America archive of top 100 prospects a while back just for fun, was that I recognized about half the names. Some of the guys at the top of the lists are well known, and some aren't. So from a dealing perspective, I'd probably weigh a prospect as about half what I perceive his upside to be, being more conservative the further away they are from the majors.
