Interesting. Meanwhile, perhaps more germane to this thread, the private parochial Wilberforce University, in the same town, with only 500 students sponsors 11 sports, which likely is over half the student body.
It's time for me to interject a thought that has been bothering mea about this discussion. Just because a school has half or more of their student body involved in sports, it does not mean that they are suckering people into enrolling just to play sports. There is a long standing belief that having a sound mind and a healthy body go together, and that education should also include physical activity. (FWIW, society in general is only just catching up, and starting to encourage senior citizens to be more active to protect their heath and their brains, but that's a subject for another day.)
Getting back to my point, at my high school, 100% of the student body was involved in athletics, because we were required to do so. I was required to participate in a sport in every season, Fall, Winter, and Spring. My Senior year, for example, I played football in the fall, swam in the winter, and played golf in the spring. I was not good enough to make varsity in any of the above, but was on JV in them, and competed against other schools. There was no goal to lure people to enroll for sports, but rather, a belief that, by being physically active, we would be better students, and I still believe that today.
