Keep in mind that Green has been the primary (and maybe only) target on the Bengals while Julio has Roddy playing on his other side. Both have had 10+ catches in a game this year, both have 2 games of 100+ yards. AJ went 4th in the draft while Julio went 6th - by the way, does that trade sting for you RBA?
Matt Ryan doesn't have the arm to take advantage of Julio down the field at this point on a consistent basis.
I think AJ Green will be the more productive player. They both have amazing physical tools. AJ looks like he's a more shifty, fluid athlete though. I personally like what I see from Dalton early on, and if they continue to gain chemistry, the Bengals might have themselves a great duo that will remind them of Chad Johnson/Palmer without all the side stuff and ego stuff.
I'll take AJ Green. He' a better player but I don't know if he will have a better career simply because he has Dalton throwing to him. Jones has Matt Ryan and probably won't see the type of coverage Green sees because he's playing with Roddy White. But if you ask me who I'd take, my answer is AJ.
I like both. Not sure who will have a better career. I think both will be on the same tier group when we rank, argue them. Hard to gauge statistical production. I just know both are ridiculously talented when it comes to catching the ball, body control.
