I'm in a 12-team, PPR league. Scoring is slightly more oriented towards yardage than to touchdowns compared to most leagues. Two RB's, two WR's, one FLEX. My first two keepers will be Roddy White and Jamaal Charles. My options for the last two spots: 

RB Ahmad Bradshaw, NYG: Nervous about his health after receiving so many carries last year. Seemed to get worn out as the year went on. Should have a large role in NYG offense. 
RB LeGarrate Blount, TB: My WW stud from last year. I love the physical running style, somewhat fresh after playing the equivalent of 1/2 season in past two years. Seems to be the only guy in TB, though PPR hurts his value rather than enhancing it. 
WR Mike Williams, TB: My late-round sleeper pick last year, he was legitimately excellent last season. He also has a legit QB throwing to him, and few other targets to compete for catches. 
WR Dez Bryant, DAL: Perhaps the highest upside of any keeper candidate besides Blount, but lots of question marks. Seemed to do better with Kitna last year, though he was hurt early. 
WR Santonio Holmes, NYJ: Solid player, especially in PPR, but I'm not a huge Sanchez fan and there are lots of targets on NYJ. 
QB Josh Freeman, TB: He was one of the better quarterbacks in the league last year despite having a pedestrian supporting staff. I really like him a lot. 
QB Ben Roethlisburger, PIT: Steady, but I don't like him as much as Freeman for next year.

I get the feeling that most of the teams in my league will be keeping their respective QB's, so I would probably be able to draft Freeman or someone similar if I don't keep them. 

At this point, I'm favoring some combination of Bradshaw, Blount, Bryant and Williams. I'm just not sure who, as I've seen these guys ranked in a variety of orders lately. Thanks in advance.
