IF you and I know that "90% of his issues are on him" (Whitney), then so does Cal and Whitney himself (going in). And, if in 5 months other kids can correct their ways, then so can Whitney. Provided a coach can coach? And, wants to coach.
Do you really think that Cal just rolls the ball out there?
Confidence and mental fortitude plays a huge role in performance (sounds like a ED promo, lol). Once you lose your mojo, it's difficult getting it back. That Whitney can no longer athletically dominate, exposes his outside shooting shortcomings. He'd fit in great here, lol.
