The poorer the student, the lower the graduation rate. If you have low graduation rates, you're probably not recruiting the best students. The best students aren't nearly as susceptible to any of those issues as the weak ones. The best students tend to stay for four or five years, even when the NFL, NBA or Major League Baseball tries to entice them with fat contracts. The best students usually are the last ones to transfer when they find themselves second or third on the depth charts.
Fault is even easier to assign.
The coaches are the ones who recruit the stud with marginal academic interest over the semi-stud with a sincere interest in graduation, but the coaches are just the easiest to spot. The blame also lays with the administrators who hire the coaches, administrators who hire the administrators who hire the coaches, and the fans. If you have lived in this area for any length of time, you probably are not surprised by that last one. OSU fans are among the most rabid in America. They are as much to blame as the coaches and administrators because they demand the athletic success that the coaches and administrators strive to achieve.
