Here's my team,

i have a score in my league 7-1 after the week 8 (i have enough advance to say that). my players are:
QB Peyton Manning

WR Andre Johnson
WR Vincent Jackson
WR Nate Burleson
WR Mike Sims-Walker

RB Chris Johnson
RB Ryan Grant
RB Cadillac Williams
RB Donald Brown
RB Shonn Greene

TE Dustin Keller
TE Visanthe Shiancoe

My week line up is the following QB, WRx2, RBx2, TE, K, DEF, Dx4. My league format is PPR H2H.

My question is : who should i try to trade to have a competitive team during the play offs?

Don't fix whats not broken. It looks like Peyton is the only one that's a lock for a playoff birth and may be on the bench in the latter minutes of the last few weeks.
