It's a fair trade but I personally like the side of your trade better (What you would be getting)
I can see the other team hesitant on accepting just because Garcon now has no Manning and his value drops right there. Either way put it out there cause it has enough to stick
I'm in the same boat as you trying to get Welker. Was trying for Welker/Brit or Welker/Colston. It's early so alot of teams don't like trading so early.
