Need help with keeper/draft strategy

[HooJet 0]

12-team league that keeps one player each year. If you choose not to keep anybody, you get first dibs on any player that wasn't kept. If you choose this option though, you automatically have the last selection of draft position.

 

My dilemma is this: I finished 10th last year (awful season) so I have the 3rd selection of draft choices if I keep either Chad Johnson, Willis McGahee, or Brian Westbrook. If I choose not to keep one of these players, I will be choosing between Tiki, S. Jackson, and Ronnie Brown (pretty much all of the other top rbs and Peyton are being kept) but will probably have to draft at the end (between 10th-12th).

 

Should I keep somebody and draft early or pickup one of the best available leftovers and draft late? Any help would be appreciated.
