A light bulb went off for me last night when Amari Cooper caught a couple of long shots downfield. It was mentioned during the broadcast as well that having a guy that demands double coverage, or over the top help makes all the difference in the world for Dallas.
I believe John Brown is perfect for the Bills and for Allen right now. Even with his successes, we clearly don't have anyone on the roster with proven skill sets that demand double coverage or every down help. That person alone would make all the difference with this offense, as it clearly did for the Cowboys.
Josh still gets WAY too amped-up in games, and it shows when he gets excited on the deep ball.
