Should I Trade QB Peyton Manning?

I have QB Carson Palmer, RB M.Jones Drew, RB Ryan Mathews, WR Donald Driver, WR Mike Wallace, and WR Chad Ochocinco... Bench I have RB Justin Forsett and RB Jahvid Best.. Carson doesnt do any good for me on the bench, but if i have him as my Starter - Peyton Manning can get me an AWESOME Wide Reciever or Running Back - What should I ask for in return? A Better Runningback or a Better Wide Reciever?
