Had a debate and bringing to the masses. Would you prefer an offensive-minded head coach or a defensive-minded head coach. Your head coach will likely call plays whether it's defense or offense, which leaves needing another coach to call plays on the other side of the ball. It feels like there are more young and "up-and-coming" offensive coaches that fall under the same branch of strategy. This means there are theoretically more candidates to replace offensive coordinators if your coach leaves. Compare that to an offensive head coach, where there may not have as many defensive options to replace an outgoing coach. A defensive coach should theoretically have a better chance of sustaining success over a longer period of time right?
