I addressed this briefly in my post above:
2018 Recruiting: - Lukas Kisunas Commits to UConn
While you're not wrong, I think this shows up
more at the NBA level, than the college level. When the athletic guys have enough skills to demolish less athletic guys. But even then, a guy like Tim Duncan, never to be mistaken for an elite athlete, rose to be arguably the best at his position ever, based largely on the strength of his fundamentals and skills.
(yes, I understand he is probably the most extreme example available)
In college, just being an athlete is not enough; bigs are generally so raw. UK's athletes in 2014 were locked down by guys like DD and Giffey. Neither were elite athletes. I mean, Giffey was guarding Julius Randle well, not because he was elite athletically, but he had very, very sound fundamentals.
When you think about guys like Harangody, Curley, etc...fundamentals in college,
at the big man position, can take you a long way.
