Yep, but that’s just the coach-to-player communication device. OC (with technically the help of a group of players/back up QB) can signal in a change at anytime, as long as you have enough time to actuate it. Ultimately, the QB should be given full autonomy, but the coaches can have full control also if they want, meaning it’s only partially on the kids. The coaches need to shoulder their fair share of responsibility in the offensive failures. They have the ability to audible into the right call, and as such, UND should be able to score more than what they did.
Many components here: execution, player talent, communication, play-calling, and syncing it all together.
