12 Team League. We start 2 QBs and get .5 PPR, otherwise standard scoring QBs: Stafford, Fitzpatrick, Collins RBs: Charles, Mendenhall, Best, Starks, Carter, Karim WRs: D. Jackson, Marshall, S. Smith, Green, TE: Hernandez, Cook
I like getting Mendy, but maybe you could upgrade with Big Ben or Crabtree. Either would improve your team. Ben might seem like a bit much to ask for, but with Peyton he's never going to start Ben, so he might be willing to package him. If not I think Crabtree is more than fair to package with Mendy.
I'd hang onto White. You have enough depth at RB to rotate based on match ups, and Romo will be serviceable at QB for the playoffs. Moss won't give you any sort of consistency at WR, and Mendenhall is just as good as the other backs you have, especially if LT hits his stride.
