Cal was reputed to be dirty, so President Lee Todd told our AD not to consider him. He was very interested in the UK job and said so in an interview that was well publicized. He kept asking his wife if there were any calls for him, meaning from UK expressing interest in him as a head coach to replace Tubby. That call never came, but Cal said he was expecting UK to contact him and would have taken the job in a heartbeat. So to say that our options were limited to the ones previously mentioned is false.
When Tubby left and BCG took the program into the dump, Cal was flourishing at Memphis and Lee Todd suddenly had a change of heart towards Cal. Then came 'the door' and the rest is history. No credible evidence has ever emerged that Cal was dirty then or at any other time. I know that this thread began by talking about the availability of coaches after Rick left, but I just want to make the point that even in 2007 when Tubby left after the season was complete, Cal was a very successful coach that was keenly interested, yet was never really considered because of spurious rumors. If he badly wanted the UK job in 2007, one might ask why he was not considered in 1997 when Pitino bolted. My guess is that he might well have taken the UK job then too. By then, he had taken Umass to the FF where they lost to UK in a very tough game. Umass was a nothing program before and after Cal's tenure there. IMO, what he achieved there and later at Memphis should have put him front and center on our radar a lot sooner than he was.
