I'm not sure if this is what the question is really asking, but on the actual roster, I'd say that Pudge Rodriguez is the best player in Detroit, in fantasy and reality. A no-brainer, in my opinion, as Pudge is almost unquestionably the best catcher of this era.
From a fanasty standpoint for 2005, I'd rank the Tigers' players:
3. M. Ordonez
9. D. Young
