Even though you don't have overwhelming RB options, you ended up with three backs that benefit nicely from the PPR aspect of this league. Matt Forte, Jahvid Best, and Reggie Bush are all heavily involved in their respective passing games. Bush's role in Miami is shaping up to be even better than what he had in New Orleans where he was decent as a PPR flex play.
Those backs are complimented by the best wide receiver in the league, Andre Johnson, and a borderline WR1 in this format: Brandon Marshall. Mike Thomas is the de facto WR1 in Jacksonville and he is on everybody's sleeper lists. I wouldn't be surprised if he outperformed Santana Moss as your WR3.
Big Ben should be able to do what he did last year over a full 16 games in 2011. The value of Aaron Hernandez is a little cloudy at the moment. Hernandez did show solid hands and incredible YAC ability last year but the amount of targets he will receive in 2011 is a bit in question. Touchdowns also may be hard to come by for the young tight end. There is some upside there, but keep an eye on the waiver wire if a tight end like Tony Moeaki catches fire.
