Respectfully, I don't buy any of what you've said here....
Rick would be down the pecking order behind Tyson, Pretty Boy Floyd, the Busch brothers, Steffi Graf, Andre Agassi....
Just because we are CBB nuts in Kentucky doesn't mean the rest of the world, especially Vegas, gives a rat's patootie about an aging, sex-addicted sixty-year old hoops coach. Tark was a special case who had been there a loooooong time, was notorious for his fights with the NCAA and eventually cuffed enough talent to be nationally relevant. Moreover, Sinatra's dead--so is Sammy Davis Jr.
A carpetbagger like Rick would have an uphill slog to get to that level in the sports world in Vegas (or LA or Dallas or wherever) today. Nor would I be so sure people in Vegas (the rank and file folk who live there) would be at all dismissive of Rick's peccadillos. That is at its core a very conservative state, a red state, and shows no signs of becoming the socially-progressive place you suggest. Yeah, in the brothel, Rick would be "just another John" but the rest of the state isn't going to be so blind.
