Do you have a source for these maps? The first one looks like the "Facebook Likes" map. I don't recognize the second.
The "Facebook Likes" map is interesting because it shows the regional nature of college sports fans. But it is also incredibly flawed. There is no differentiation for a Facebook like that is caused by the football or basketball team (so you can't tell if the Syracuse likes are people who are Syracuse football or basketball fans). There is no timeframe for the likes, so someone who hit like 5 years ago when a team was making a run is still counted as a like today, even if the person no longer has interest in the team. And of course, schools with Facebook promotions (e.g., running contests which require hitting "like") will have a much higher like count than schools that don't run Facebook promotions.
