I am more worried about shultz and dooley.....i mean collins in the passing game. Diggs has basically been running about 6 to 8 yards catching a ball and diving forward for whatever he can get. He has shown no explosiveness at all and looks to be a slot guy to throw slants and quick stuff to.
Biggest thing for Buffalo is stroud will stand there and hold the ball forever and he will give you opportunities to hit him if you can cover long enough.
