Not only with Diggs Production. One thing to look at is also how much he opens up the field for Brown. Granted Brown is an excellent WR to get open himself as well, but what are you going to do with these two. Jets played alot of Cover 2 because both Diggs and Brown can take the top off, that opened up the underneath and screen games, because they played so much cover 2.
Watch what happens when there isnt 2 safeties over the top of Brown and Diggs. I also knew Diggs hands were good, but dang when was the last time we had a WR that took the hits he took all game and held onto the ball?
