Powerrankings for Football

#1
This is my 1st post and decided to register. Just wanted to say there is a lot of smart people running around here and i love reading the articles. Thanks guys for all the info.


My question is what do i need to know to create powerrankings for sports. I am absolutly fascinated with this concept. I just have no idea how to do it. If anyone can help i would appreciate it very much.
