Yes but I think that the balance comes from being good on both sides of the ball, not just being balanced. Get a lead, play good defense and you then tend to run the ball to keep the lead without the fear of bad a defense giving it up.
Any team can be balanced by just by calling plays that make you balanced.
You call plays to win the game and winning teams just end up being balanced because of how the games play out. Winning creates balance, imho.
