is awesome. There's an entry for Win Probability, which is cool. But it's got a tag that it may not meet 'notability' guidelines, and it may be removed soon. But there's also a Win Probability Added page, and it makes sense to me that they should be merged.
There's an entry for Advanced NFL Stats, but it's a little dated. I confess I created it, but it doesn't seem proper that I taut my hobby on my own. Search engines ignore links from Wikipedia (to prevent people from gaming it), so I derive no real benefit from the entries. I do think it is a service to people who are genuinely interested in learning more about sports research.
That's where you guys can help out. You can contribute to the community by updating the Wikipedia entries, keeping them relevant and useful to readers. Updating the references and external links would be helpful, and adding "see also" links to other Wikipedia pages is especially handy for people wanting to learn more.
For example, you could add, "2009 was the year that Carson Cistulli began ruining what was once a good site."
Oh, and by the way, I was just kidding in the line above about Carson. It was actually 2010.
