Wes Welker and Maurice Jones Drew for Larry Fitzgerald and Pierre Thomas?

HELP! Should I accept this trade or not? I really need a wide receiver and I have a lot of good running backs-- I have Marion Barber, Joseph Addai, Ray Rice (super sleeper), Earnest Graham, and MJD--but i want to trade jones drew to get a really good receiver--my receiver core is wes welker, hines ward, and kevin walter with donald driver on the bench
