If there's one thing i learned from the Callahan era it was you can score 70 points and still lose a football game, 21 points should be more than enough to win any game. Offenses are for scoring defenses wins games full stop. Frost needs to do what ever is needed to fix the defense first be it fire a coach or two or trying the next guy in the depth chart. He is making the same mistake Pelini did hes being too loyal to his friends. If they aren't producing results get rid of them. The good ole boy club isn't good for any team chemistry whether its business or football, Its self serving. Fix the defense then you can get cute and score a million points but, for Gods sake get the basics right first.
Get your points grind it out keep your D fresh and let them win the game.
