QB: Philip Rivers
RB: Ray Rice, Beanie Wells, Tim Hightower, Clinton Portis
WR: Randy Moss, Donald Driver, Piere Garcon, Legedu Naanee, Demariyus Thomas, Mike Williams(sea)
TE: Visanthe Shiancoe
D/ST: 49ers
K: Robbie Gould

I plan on dropping Williams and picking up Keiland Williams but he's on waivers till tomorrow. I know I'm weak at RB and have too much depth at WR but in this league almost everybody's weak somewhere. I'm trying to sell Hightower high but ESPN put right on his status "sell him now while his values up", thanks for blowing up my spot. The starting positions look like this: QB, 2RBs, RB/WR, 2WRs, TE, D/ST, K and 5 bench spots and 2 IR spots. I appreciate anybody Ranking my team. I'm also new to this forum. Thank you.
