Just a few notes.....as compared to my list:
1. I would move Smoltz down a few notches, just because of injury potential. My 2-3-4 were Wagner, Smoltz, Foulke, with serious thought of Foulke before Smoltz
2. For similar reasons, I would move Percival down 2-3 spots, and Hoffman down 3-4 spots.
3. I like Rhodes and Benitez better than Jorge Julio. Yes, they both have some concerns, but I believe are still lesser sins (and have better WOW STUFF that J.J.) And for that matter, I like F-Cord better than Julio too.
Good distribution of closers-in-waiting versus actual talent, and putting Nen near undraftable (at this point anywho) is wise.
When ranking closers, its tough to balance guys w/ jobs, versus better quality pitchers (the biddle versus ayala, or Koch versus Marte, or Wagner vs. Graves controversy). But I always try to get the better pitcher, even if he might not be the closer. I'd rather have a setup guy who MAY get the job, than Rocky Freaking Biddle, who (possibly) might keep the job, but mess w/ an otherwise solid ERA and WHIP.
