Lucky 5-1 team, how to keep it up? WHIR!

[Weasel_King]

12-team standard league, had misfortune of drafting Charles but due to some lucky scheduling I'm 5-1 (with only slightly above-average points in the league). Have been active with the waiver wire pick-ups, here's the squad:

QB: Tony Romo
RB: Matt Forte
RB: Shonne Green
RB/WR: Ryan Torian
WR: Hakeem Nicks
WR: DHB
TE: Brandon Pettigrew
K: John Kasay
DST: Matchups

Bench:
QB: Matt Ryan
RB: James Starks
RB: Maurice Morris
WR: Sidney Rice
WR: Mario Manningham

My flex spot had been a problem, but now with Hightower out I think Torian will be a solid #2 RB and can effectively take over the flex. I think a weakness on my squad is the second WR slot, but I think between the potential upsides of DHB, Sidney Rice, and Manningham hopefully one of them can emerge as a solid starter (have been pleased with DHB as well as with the Palmer addition, though Palmer performed absolutely terrible this week). Any thoughts on how to improve this team?
