For coordinators we would only play with your side of the ball. So if you were an OC then you would play with only the offense and you would super sim on defense. Of course I would have no way of policing this and in user game it would be normal, but all of your goals would be directed at your side of the ball, and maybe how well your side of the ball does as opposed to your whole team. Like say you have the top offense but lose all your games well you would still be able to move to a head coaching job. Also for recruiting we would have no restrictions while you are coordinator, but you would only be able to add players to your recruiting board that are on your side of the ball, and the CPU would have to recruit the other side of the ball for you. Then of course once you gain enough points you can become the head coach of a smaller school.
We could even start out as say the offensive coordinator of a four star team then move down. I don't know, I am just throwing ideas out there.
