Adding a school because of a coach is the worst reason possible to add a school to the conference.
I have often wondered if they would have been tapped over Memphis if the Bob Huggins incident happened a year earlier. I think in the case of sports like basketball, the coach IS the program. What are you going to do?
Presidents know that coaches come and go but there has to be the committment from the university to support the programs in tough times.
However, having said that I will certainly admit that it certainly didn't hurt but Cincy had many other things that appealed to the BE. They showed a serious committment to improving their academic and athletics. Zimpher wanted to increase Cincys academic and athletic stature. Look at how much construction went on there for the past 10 years or so including Varsity Village.
Cincy also fit in the the nature of what the BE wanted to become. At the time, BE FB wanted to split and they would essentially have two quads - the Ohio Valley quad (WVu, Pitt, UC, UL) and the NE quad (BC, Ru, SU, UConn). UC also brought with them an instant rival in UL and with the proximity to Pitt and WVu, it was hoped that they would develop rivalries with Pitt and WVu.
Time and circumstance said that Cincy was the better option at that time. They seem to be a really good addition to the conference in the area where it needs help - FB. I certainly don't have any complaints about the 'new guys'. They certainly have pulled their own weight. Now, Pitt and SU need to step up.
