Is there data to support the argument? Probably not. And it surely does not explain Young having 9 at half time and being benched the entire second half.
Nance is a kid who grew up playing guard. Who still, today, shows he is much more comfortable facing the basket than with his back to the basket. You can see why CC likes him playing 5. You go back to any year of his tenure and you saw, for example, Pardon, over and over again, at the top of the key, often awkwardly waiting for a passing lane, a guy who can't shoot the 3, should be fed in the post more, but is stuck trying to create space, which ultimately he does not because his defender stays inside. Now you have a guy who teams actually have to come out to, creating space, can shoot the three... sounds like heaven. Except you still need to rebound, ideally it would be Nance with 4 guards, if said guards could rebound well, Baylor 2020 style. As they can't, you put Beran out there, which last year was not enough to rebound decently, and, to make things worse, is a stiff on offense who lost his confidence from 3.
So the conclusion is that RY does not fit the threatening 5 on the outside creating space mold, so he does not play as much as he should. It's an offense designed for 5 players comfortable playing facing the basket. One that Villanova or Baylor made very successful. Works with very athletic players, NBA for example is full of them, who rebound well despite not being post players, who are good slashing off the dribble. Players we usually don't have.
