Should I accept this fantasy football trade?

IMO the trade boils down to you getting Marion Barber and David Garrard for 3 chumps. I don't have any faith that Campbell will be an all that great fantasy option. Mendenhall's valued is almost entirely based on whether or not he gets goaline carries and Parker getting hurt. And I don't believe Gin Jr. will amount to much of anything in Miami this year. You might have 3 Dallas players but they all produce pretty consistantly and you still have MJD for a bye week. Better yet, turn right back around and see what you can get for whoever you decide is your odd man out RB. All in all, Barber and Garrard for nothing sounds like a super deal to me. Do it up.
