I have liked this site for a few years now. I watch it mostly for hockey but it is fun for football too.
According to this site, if the Bills win out at this point, they have a 68.3% chance of making the playoffs.
If they win only 9 of their remaining games, this drops to 10.6%.
Before all the homers start complaining and talking about this stat or that stat or "buying into the system", this is just for fun.
But for hockey at least, it has been pretty accurate the past few years.
