People usually don't want to talk about how small of a sample size 16 or 17 games is for evaluating the quality of a football team based on their record, and how hugely variance plays into this, more so than a 162 game baseball season or 82 game hockey/basketball season.
This is why peripheral statistics are way more useful in football in terms of making predictions than in other sports. I guarantee you that Vegas sharps don't see a 9-6 team when they look at the Bills.
