His poor strength, average athleticism, & non-physical playing style — are eye-catching in the wrong way, though.
That said, I could see Jax turning a solid Senior season into a better Draft showing next season. He might not be a strong athlete, but I'm convinced he's quick enough to guard in the NBA with his length.
He's definitely gotta hit the weights hard & prove he can be a guy who can get to the rim & put his high FT% to much better use next season, though. A guy I'd sit him down with in a film room — is Lee Cummard. Jax does quite a bit of things better than Lee — but physical play is one thing Lee did much better with very similar length, frame & athleticism to Jax.
