From where it was with Pete Carmichael, it is by far 1000% better. No one was complaining about Kubiak's offensive play calling after the first 2 weeks. Then injuries happened and happened again. Can't blame Kubiak for this. If the injuries had not occurred, records were set to be broken. And this was with Carr as the QB. I believe Carr is at best an average QB. With the Saints he has 0 two minute game winning drives. He is horrible under pressure. Yet, when given time, he is actually pretty darn good. Good deep ball, strong arm and accurate when given time. Can't throw on the run.
I only state this about Carr to emphasize that Kubiak is dealing with an average QB, and for most of the year a make shift offensive line. Yet, when he had the entire line intact, with this very average QB, this offensive averaged 45.5 points per game. (Only 2 weeks).
So Kubiak has done a great job with the cards he has been dealt. I would love to see him stay on with the new coach, get a stable offensive line and a above average QB, preferably a mobile one, who can also pass on the run.
