Gordon, Butler, and Pelfrey are definitely a league of their own. Zumaya (from a fantasy perspective) is only going to be worthwhile if he becomes the closer, which hopefully happens at some point this year, but is unlikely because they are doing well, as bad as Jones' ERA is, he's not blowing many saves, and Leyland is one of those "veterans deserve the job" kind of guys.
In fact, I wouldn't be surprised if Jones also starts '07 with the job in Detroit.
Kemp and Morales are ahead of Pie just because they've actually made it. Pie, I'm not sold on at all.
