Absolutely not, #1) there are a lot of OCs who if Kirk gave them the reins could get this offense to move and score some points, maybe only 17 to 20 a game but usually is enough. Mich's OC is lighting it up with a similar type offense, much better talent, but I would say a lot better offensive coaching
#2) you can never lose a game if the other team doesnt score so it is better to have a great defense and as they say defenses travel well to away games because communication is not disturbed as the away game crowd is quieter when the defense is on the road
