These things can be taught. You looking at all these kids as static quantities is weird. Some kids might get a lot better than others, but it's possible to learn.
The prior regime either taught very little of this or weren't effective at the teaching; the results were easily observable. The current group does, and you can clearly see the results with Carlton/Whaley.
Some guys can't learn sure, but that's not the majority. As we've said, Kentan came in playing only a few years. So had supreme upside to learn these things. He had significant upside potential, but unfortunately learned very little.
We saw him break out a bit as a Sr. That means he was capable. If Hurley had him from day 1, I'm willing to bet we would have seen that sophomore year...and then greater heights reached as a Jr Sr.
And fwiw, Enoch, who averaged 10/6 last year, apparently had a great offseason. I'm not saying he's great, but he made much more improvement at Ville than he showed at UCONN. I'll be interested to see what happens to him this year.
