The D was good. But so was the O. I don't think there is currently a gap of any consequence between KC, Cincy and the Bills. As to the subject of this thread, I think each team has improved in their own way, but the improvements for us on the OL will have a bigger impact than a new wr or te. I don't think we are going to score considerably more than we did last year. So, imo, finding a way to prevent the other team from scoring 30 points will be key.
