Do you have a site that has the complete list of your rankings that are on a graph? I'm sorry, but my lone issue in this and any others is that it can be pretty hard to read. I know it's difficult to type it out here to look organized.
A possibility is doing a promotion/relegation system like they do in Europe with their soccer clubs with 120 teams.
But, I go with Vernster, every team should be evaluated on the body of work over the framework of the current season.
