Id do it. You have plenty of depth at WR. Julio is good but he has been as up and down as they come so far this season. With Welker back into the mix in New England, Harvin a fantasy stud and always must start, decker almost an always flex start with Peyton picking defenses apart, I see no downside to this trade. In the end your team will be better for it. The hard part will be getting the other guy to get rid of Gronk. I have him on my team and know I wouldnt.
