So Wikipedia suggests that the AAFC Bills we're actually named after a popular Buffalo barbershop quartet of the era (of whom was named after the frontiersman Buffalo Bill Cody). It is also suggested that Ralph got his name from the AAFC team. So, are our Bills an homage to a defunct singing group too?

For those curious, here's week 3:
We're #1, woo.
Sorry for the double post, but we're also mathematically #1 on Football Outsiders as well: http://www.footballoutsiders.com/dvoa-ratings/2011/week-3-dvoa-ratings
I know the kid who is putting this list together is still working the kinks out of his/her formula, but it looks like he/she is at least attempting to account for strength of opponent with this part of the formula: Total points is calculated by ((winning % * 1.5) + (pt diff / 50) + (off stat) - (def stat) + (rush stat) + (pass stat) + (spec stat)) + (avg of all previous opponents totals / 2)
Based on statistics and the formula used by the original poster, 5 is accurate. I guess there are pretty wild swings in the rankings until week 4-5 though.
