Richie, I’ve only been doing this for about a year (and considered myself fairly adept at Excel as well a year ago – but the amount I’ve learned about in the last year has been loads more than I knew 12 months ago). Somewhere via a google search, I ended up finding out about Wayne Winston (try “use solver to rate sports teams” as a start) and ended up buying his book Mathletics. Doing the Winston method (described in his Microsoft Office tutorial) will essentially get you the same numbers as the SRS for the NFL, but won’t split out the MOV or SOS components (you just get the SRS rating). Found out about the SRS about a year ago as well, and only figured out my mistake in Excel about a week ago (so am still learning about it).

George, what sort of Excel tools do you use to calculate the NFL SRS? I consider myself fairly adept at Excel, but I wouldn’t even know where to start in setting this one up.
