This is my first year in this league, you can only carry four RB's= two starting and two bench. My RB's are FWP, Clinton Portis, ADP, and now Chester. I really debated this one considering MJD's recent production but ultimately couldn't pass up on the matchup this week against Oakland, and if ADP is out for a considerable amount of time I'd rather have a guy thats guaranteed the rock than one that is splitting time with 1-2 other guys. Thoughts?
