Why? Who cares what his feet look like. Like you said, his shot is quick. Good release. Good athlete. Quick off the floor. He defends. Has some nice passes. I couldn't give two ***** about how his feet are positioned.The feet positioning issue is a legit issue. Otherwise the tape is exactly what you want to see at the Power 5 level.
I know another guy that shot jumpers with his feet close together. He's currently the best backup point guard in the NBA.
