Besides having a limited number of offensive formations you can read with a high frequency of accuracy what type of play being called ( run or pass) base on the personel they have on the field. You would have to be at the game to pick this up, but if I can see it I am sure their defensive coordinator can see. I believe there were at least 3 times that both DJK and McNutt were not in and we ran everytime and not very successfully.
