In a general fairly unspecific order, I've got the top 15 as RJ, Schilling, Vlad, Soriano, ARod, Bonds, Pedro, Pujols, Sosa, Giambi, Mags, Berkman, Beltran, Helton, Piazza.
The one guy I would drop out of there is Piazza. Although he's averaging the #18 pick on ESPN's LiveDraft, I think he is considerably overvalued. His numbers have been declining, he's got tons of miles on him as a catcher, the Mets suck etc. etc.
It's also a bit early for Beltran.
In any event, I'd at least strike Piazza and add Tejada. Others who wouldn't look too bad in the #14 slot include Nomar and Zito. For my money, though, I'd stick with one of the ones you listed, drop Piazza and Beltran, and pick up Tejeda. Those are your 14, and any one of 'em will do ya fine.
