If they are both retained it brings up the question of just what is the product the company (Buffalo Bills) makes? If the owner and his managers see the product as "games," then the company is successful since they produce sixteen + games a year and make loads of $ doing it. If the product is wins, playoffs, and championships, the company is a woeful failure. I believe that there is a fundamental disconnect between the company and the fans--the company produces successful games (makes $), but the fans believe the company is seeking to produce wins, and that ain't happening because the company won't endanger the bottom line by bringing in the people needed to make games that they win.
Again, if the top guys stay or go, it makes no nevermind until the ownership, and thus the fundamental objectives, change.
