I appreciated it and thought you had some very good points.
Item #2 in your disappointments section is weighing heavier and heavier for me and why I would rather see the Bills move on from Ryan. The continuity argument only works for me if there is some sign of improvement, and the defense is not any better in year 2 under Ryan. If they had even taken a step up to, say, #10-12, I could see it.
So while I don't think 9-7 would be a crushing disappointment, I hope that management will make a realistic assessment of where the team stands, and ask if they have actually improved in any respect from a year ago, or are they just spinning their wheels. I think if you look at it in that way, the case for making a change is pretty strong.
