I get your point on Caris, I just don't agree. As a sophomore, he was still growing into his body. He stumbled a lot handling the ball, had a good but not great three point shot, and still really needed to work on vision. So for me, he had great potential, but was far from a finished product. So I don't think he was ready for a dribble drive system.
Now, he's much stronger with the ball, and his vision is outstanding, and I think much of that came from passing the ball out of the pick and roll. I think our system really benefitted his skill development, which is now evident in his pro highlights. Just my opinion.
