the ball more.
We would have been undefeated last year.
And the teams that were in the games late, would have been put away early.
Finally, I respectfully disagree with your assessment that the defense has won "many of those games." I would like to submit for your consideration that is was the offense that won most of the games. And, if they had the ball more, none last year would have been close.
Since no one has been able to stop the offense, take some more risks on defense, and get the offense the ball.
