I wasn't aware of the HBCU agreement. Makes sense. However, I entirely disagree with many of the comments that you can't really tell the difference between a team who will be in the 200's vs the 300's. This is actually VERY easy to do. Heck, teams that simply just play many big conference schools, are likely to be in the 200's, or even 100's.
It's also very easy to look at historic trends and see that most of these HBCU's and teams in certain leagues will always be 250+ or 300+.
For instance, it's pretty clear that if you play a middle of the pack team from the MAC, Big South, Sun Belt, MVC, etc, you won't get a 300+ team. Even those schools, who might not even go .500 on the season, will still end up like 190th.
