QB is a tough call, I also have Cutler, if only he had the targets that Schaub has, oh how sweet that would be...but I guess you go with Schaub, I've just gambled on Schaub the past 2 seasons and he is marginal.
Schaub has the weapons to make me think that he'll post bigger numbers then Cutler. The fact that Andre Johnson could go off for 150yds and a TD or two seems more attractive then Cutler to Hester or Cutler to Olson.
For RB Id go with Barber but im in PPR league. Id be a bit concerned with how much action Barber sees. I say that because Ive heard some things about Felix Jones having a bigger role in the Dallas Off. I think Portis is the safe pick. You know hes the man as long as hes physically able.
Cutler. Playing against an easier defense in GB and Cutler makes his WR's better not the other way around. Not sure what is wrong with Cutler's weapons as well he has a great RB that catches passes, the best receiving TE duo in the league, and a burner in Hester.
