Too much money involved in both NFL and college football for the outcomes to be not somewhat controlled. I don’t believe that the teams could convincingly “script” a game as described - too many players involved and someone would squeal. But I do believe that the desired outcomes are dictated by the gambling interests and controlled as well as possible through front office, medical and officiating decisions, without most of the players’ knowledge.
You only need a referee, coach, quarterback, running back, or wide receiver.
