I'm no pro at uploading files for public view. hopefully this is enough: Google Doc here
It's three years of NFL data in eighteen categories, correlated to regular season wins. If you see these data and would like more, or different, just let me know what you want and I'll see what I can do.
Also, if anyone knows a better place to find data than NFL.com or ESPN.com, please let me know. I might even consider paying for a subscription to some site if it is good data and not overly expensive.
