Boy - I would feel pretty positive about this roster if I were you! Can't speak to IDP, but WR is SICK w/ White, Fitz, Sims-Walker, and Floyd and you Peterson & Addai are solid RBs. Favre, we'll have to wait and see - but you have good coverage w/ Ryan, and he may end up your starter.
Good luck, see my post if you have a minute.
