It's based off of a very well thought out formula that for the most part looks at your returning juniors, sophmores and freshmen. When they first came up with it I thought it was way way overkill but in helping out with compiling data the first year, it really makes a lot of sense. As with anything there are pros and cons but in the end the best teams are crowned, at least in my opinion. I'd like to see someone come up with something better if people think it's so bad......
