Athletes are not the only people who receive financial assistance and leave
without graduating.  It happens amongst the general student population all the
time, and yet we do not ask for their scholarship money back.
 
While one might wish to argue that the school gives the athlete a springboard
to fame and fortune, the non-athlete non-graduating scholarship student is
exactly leaving without having accumulated any benefit either.
 
But when it comes down to the bottom line (i.e., money), the school makes out
like a bandit whether or not the athlete graduates.  In the short run, while
Holzinger is at BG, more people will go to the games to see him play generating
more ticket revenues.  In the long run, the whole school benefits - because the
award winning Holzinger went to BG, more people will have heard of BG, and the
more press the school gets, the more likely enrollment will increase . . . .
