Dynasty League trade, please help

[triple3play]

How would you rank these pitchers in a dynasty league: Haren, Billingsly, and Clay Buchholz? Should i trade Buchholz for one of them, or does he have the most potential going foward in dynasty.

I think Haren is well ahead of the other 2. Then Billingsly, then Buchholtz a distant third. Even in Dynasty you have to take into account what they have done at the ML level. If Buchholtz was in the NL I think it would be closer with Bills but that's how I have them.
