I think he is wearing down. That accounts for his lower FG%.
His fade away has been consistently short but on target all year. He is just pulling the string on the shot a little. This is easily fixed and I think it will be a weapon next year. His form is very good. He has made good strides with his game since his freshman year when guys repertoire consisted of a drop step and a running hook. I think he can make another big leap next year.
