Can you elaborate on this? It doesn't sound like it has any reason to be some secret. PQ has been involved with UR for quite some time, it certainly pre dates Mooney. That is a fact. He may be buddies with Mooney and Hardt and his involvement has increased, which is natural to lot of extents, just saying - and I could be wrong - I wouldn't expect him to go anywhere over personnel.
Well, his money will always be present on campus. There is already one building with his name on it, another will be started soon. Both he and his wife are grads of UR.
But relationships are a different thing. Personal connections, family connections, etc. often change with time. Sometimes it is just the nature progressions of life that bring about these changes. So in time my guess is that things will change for him and he will move on to other things. Do you really think he comes to games because he enjoys basketball that much? If he did, one would think he would not like what he is seeing. He just might take his friend aside and make a suggestion or two about how to improve the program.
No, my guess is that he has "other" reasons to drop by the campus.
