I'd go with Murray+Ridley at RB and Decker at Flex
8-man PPR league
QBs: Brady RBs: Foster, Charles, D. Martin, Murray WRs: J. Nelson, Fitzgerald, Bowe, Nicks, T.Y. Hilton, M. Williams TEs: Graham, Hernandez K: S. Graham DEF: Texans
10 Teams PPR League QB - M. Ryan/ T. Romo RB - D. McFadden/ M. Forte/ B. Brown/ K Moreno/ W. McGahee (Gone)/ C. Benson (Gone) WR - V. Cruz/ P. Harvin/ / G. Jennings/ D. Alexander/ C. Givens TE - A. Gates/ H. Miller/ J. Tamme
RB1: MURRAY, No question your number 1 running back should be Murray. He had a great opening week and I think cowboys will look for him to do much of the same against an unproven run defense in the seahawks.
RB2: RIDLEY, NE will defintely look to run the ball more and get him involved.
FLEX: DECKER, I like Decker here, although I wouldn't fault playing lynch instead. I think Decker has a better matchup and will get lots of recptions in a game that could be very high scoring. Decker's value rises for ppr also.
12 Team 1.0 PPR (2-2) QB: Newton, Wilson RB: CJ2K, T. Richardson, D. Brown, M. Bush WR: J. Jones, Lloyd, Blackmon, Hartline TE: Finley D: 49ers
