Normally I would say in a PPR league McCoy is better. However, I worry about his production with Vick at QB. His worst game was the only one where Vick played the entire time. If Vick remains the starter, I would pick Mendy between these two even in a PPR.
QB - A Rodgers, E Manning
RB - A Foster, S Jackson, R Mendenhall, T Jones, R Bush
WR - G Jennings, L Fitz, S Smith (Car), P Harvin, V Jackson
TE - A Hernandez, J Tamme
