Payton knew that whichever quarterback he decided on — Hill or Winston — would lead to a specific and different type of game plan. The longtime coach went with the quarterback whom the Saints assured last spring — as he was signing his two-year extension — that he would get a chance to start if Drew Brees ever got hurt.

I might be wrong - but I'm guessing if there is a specific and different type of game plan for Hill or Winston, then there is also a specific and different type of game plan for Brees and Hill.
