It's a big reason why people are asking about the four vert play still being overpowering, because it seemed last year it was the only thing that worked with any real success.
I dunno about that statement. I agree it can be real aggravating when you run 4 straight passing plays from 1 shotgun formation then try and run a HB Draw from the same and they crush you. But saying ONLY 4 Verts was successful isn't accurate.
I could chose one game to pass every down then one game to run every down. And I never ran 4 Verts
