What I get from "real world" interactions (meaning, live and not on the internet, which isn't even a real place I don't think), is that any fans that have left the program didn't do so over OAD. To be sure, folks are definitely tired of it, it doesn't produce like it did and all you have left are (present year excepted) good but not great teams with near total roster turnover. Not appetizing. The people that have left, who have said I'm done with UK basketball until Calipari leaves - and I don't think that's a significant percentage, by the way - are the ones mad about kneeling/social justice issues.
And I'm not sure what there is to do about that, can't put the genie back in the bottle.
Point 2. Let's assume none of the assumptions I see about Cal here are true - let's assume he's not stubborn, arrogant, resistant to change, etc. Moving from a OAD model to something more traditional will be very difficult. I've said this before - I always worried about the next guy after Cal. Cal retires, the recruits decommit, all returning players leave early. The next guy is in a world of hurt, and likely for several years. Now we're faced with changing mid-stream. How do you do that, exactly, and not have a period of, well, bad teams? How do you get from here to there.
I don't really entertain serious thoughts of wanting Calipari gone. First ballot Hall of Famer, coach of the decade, yada yada. He ain't leaving until he's ready (just like K, Roy, Izzo, etc.), so I don't even think about it.....
