Pricing for the DH is another animal entirely. Bradley will always be the best value at DH, because he is the worst defender in the set. I would rather price everyone appropriately to play in the field, as opposed to forcing certain hitters to be priced only as DH's. Effectively when the worst defenders are used at DH, their negative fielding component in their pricing is no longer applicable.
What improves Bradley's value further is his high injury rating and the additional discount that brings.
