From what I heard, it was a little more complicated than that. The University wasn't happy with where their med school stood so they started pouring more money into it. If you've been there, you've seen their gorgeous new hospital complex. It is incredible. Anyways, since they spent so much money on the med school to improve it (and it looks like it worked, their ranking has improved) and compound that with the overhead of a Dental School, there just wasn't money left.
