Love the Peyton-Gore-Greene combo in your starting lineup. That'll treat you well all year.
Solid WR depth but possibly no true WR1.
Might be lacking RB depth too, depending on how Spiller pans out and how many carries F. Jones ends up getting in Dallas.
Overall, above average. Would stand pat for now and see how you do, then trade Peyton for a still solid QB (Romo-Rivers-Schaub tier)+reinforcements at other positions if you really need it mid-season.
