6-0 -How to improve?

[RexRules]

Currently 6-0 with the most points scored. Pretty big money league, so I try to constantly make deals to improve my team.

10 team league.
We start 2QB 3RB 3WR 1TE 1K 1DEF Pretty standard scoring except passing TD's are worth 6 also.

My main draft goal was two top tier QBs solid RB's and high risk/reward for the rest. I took as many other starting QB's or Backups in unsettled situations as I could and I have been trading them off for useful pieces. Last week one team was left with only one available starter and I was able to turn Matt Moore into Kevin Kolb, then this week traded Freeman, Harvin, and Ponder to the same team for Nicks, Jets DEF and Moore (last week they started Moore and Mcnabb). Earlier in the year I traded Lesean McCoy and Schuab and got Vick and MJD in return.

Anyway, besides all my byes this week i'm starting to think I might be pretty set for the rest of the year. But if someone could come up with some ideas to make my team better I would appreciate it.
