Hardest decision of my life right now!!!!!!!!!!!!!!?

I have been offered Peyton Manning, Lendale White, and Plaxico Burress for Joseph Addai (I have Addai)............But the thing is I already have a good QB (Tony Romo), and my RB's are decent(Maurice Jones Drew, Edgerrin James, Marion Barber III, and Brandon Jacobs), BUT I feel I am lacking a good #2 reciever, I have(Reggie Wayne, Torry Holt, Larry Fitzgerald, Hines Ward, Anquan Boldin, and Joey Galloway).............I am very confused and am having problems deciding whether to accept this offer or not...............By the way, Joseph Addai is my favorite player on the team..............Should I accept this trade or not???????
