I think it's CJ then Julio. Julio is the second best receiver in the league IMO
I think Julio is a stud but would take CJ over him still.
Fitzgerald is still arguably the best receiver in the league. He isn't the physical freak that Megatron is but that doesn't stop him from being elite. Megatron has put some distance between the two of them, but much of that isn't Fitzgerald's fault.
Personally, off the top of my head I would order it: CJ > Fitz > Green > Julio
Brandt is just trying to get attention.
