If, as I expect, the bills have a winning record, then they better keep the entire staff, including coaches.
I for one think the trashing of Hackett, and by extension Marrone, has been stupid. It's amazing what winning does to make play calling look good. The bills did not lose games due to play calling last year, they lost because they started three green QBs, had no depth at CB, played lousy STs, and couldn't stop the run. The play calling in Chicago was essentially no different than it's been. The bills won because of stopping the run, great STs, and depth at CB. If EJ can hit the deep ball opportunities that are set up by hackett's conservative-looking play calling, the bills will win a lot of games, and the coaching staff should keep their jobs.
