How does my roster look for the ROS? WHIR!

[cds4446]

This is my first year playing and I am in a 10 team 1pt ppr league where we start 1QB, 1RB, 2WR, 1TE, 1FLEX, K, DST. How does this roster look for the rest of the season? Is there any improvements I can make. Let me say this league is not into trading at all. I have made numerous trade requests and they are rejected every time, even when I think I am giving away too much. Everyone seems to be set with their rosters or those with holes in their rosters have nothing really to offer. I am 8-0 so my waiver priority is always last every week, so its hard to grab the good wire pickup. Just trying to get a fix on the playoff picture. Here is the roster I currently have. the only position that rotates weekly is defense. Thanks


QB: Peyton, RGIII
WR: Cruz, Denarius Moore, Britt, Amendola
RB: Murray, Mcgahee, Spiller, Rashad Jennings
TE: Gronk, Witten
K: Gostkowski, Shayne Graham
DEF: Chargers
