i've been looking at a lot of middling sort of prospects...the sort that disappear with great regularity, but occasionally come to prominence.  these guys all have some chance to do well, and range anywhere from andy oliver's 2nd round selection to "who?" (for me anyway).  i'm wondering what you guys think of their individual chances, including "blockedness" by levels above them, just making it to the majors, or really having some level of impact.  i've read various blogs, looked at stats, and can't make up my mind about any of them.  the one thing they do have in common is they all made the 2010 top 20 for their particular team...although, as we all know, top 20s look much different around 15 for different teams.

without further ado...
