Re: How improve offense?
I feel the answer is very simple, pace. If Kubiak had any sense of urgency or any ability to change the pace of play other than "oh crap we're losing by 30, speed up now" we'd be much better off. Why do we continually allow the defense to substitute? Go muddle a few drives a game before we're down by 21. Change the pace a few times, allow your offense to get some momentum.
I intend to live forever... so far so good.
