Since the 1998 season, the Buffalo Bills have had four head coaches (1997 being the last year that Marv Levy coached). Essentially, each coach has had three years to try and put this Bills team in the playoffs (and, in far dreamier parts of the plan, win a championship. The lone exception was Mike Mularkey, who only gave himself two seasons. Wade Phillips was the only one of these coaches to get us to the playoffs, and he did it in the first two seasons after Levy retired. Every season since then, this team has not been able to play games past the regular season. This is why I believe that a fifth year of Dick Jauron might be the best thing for this team.
Take a look at Jeff Fisher, a very respected and tenured coach. (I doubt he will be gone after this season, even if his team only wins 3 games.) When he first started coaching the Titans/Oilers in 1994, he was promoted mid-season to head coach. Finishing out the season a very dismal 1-5, the Oilers decided to retain him the following season. He then went on to produce a very Jauron-ish 31-33 record over the next four seasons. The years that followed made Fisher's career. In 1999 - a season that will burn in Bills history forever - Fisher put together the missing pieces and assembled a team that lost the Super Bowl by one yard. Just to make sure it wasn't a fluke season, they went on to finish the next season 13-3 as well.
I understand that Jauron's coaching history is terrible, but so was Bill Belichick's as a head coach before coming to New England. My point is that I feel that this team is a GM and a few players away from getting over that hump. I really believe that Jauron has started to build this team in the right direction. A good draft, and a decent free agent signing or two, and this team will be a serious contender. But all this will be negated by a regime change. We've seen new regimes gut this team before, and it has yet to work. Continuity is a key reason I think that Jauron should come back for another season. It is also one of the reasons Ralph Wilson brought him back in the first place.
