I can't remember a Bills game when I wished that the opposing team would score 50+ against us, while the game was in progress. That way, there wouldn't be any guessing or carping about whether or not Jauron would be fired, it would just happen.
Even if you install a bad interim coach for Jauron, it might wake some players up, especially if the new coach started coaching instead of some kind of bizzaro Miss Congeniality contest. Most of the players on this team wouldn't make another squad in the NFL. At the end of the season, replace the interim, who will, no doubt, be unable to turn things around, with someone of esteem.
Sack the organization too. Brandon can be kept on to do the thing he was trained to do - marketing. Lock him in his bloody office.
