I think you can still have issues with what happened last year and praise him for this year.. (if this offense turns out to be as good as it looks this year)
My issue was injuries and talent completely shut this offense down last year. It came to an unacceptable level of ineptness..
A great OC would have figured out how to generate some offense last year. I can accept there will be years where the offense will be up or down. But, we should never be falling down to the 100's nationally in offensive production.. If we do, he's to blame. Just as he's to be credited when we're good.
