His stats last season are all you need to look at. He had plenty of minutes and took lots of shots. He was not hampered by BP in the slightest.
The reason(s) for his in-ability to succeed are all on him. Pointing the finger at the coaches over this is really petty...
According to Hoke, Aden was third in shot attempts, second is usage and first in 3-point attempts (by 50!). Additionally, he was 11th in FG%. The stats speak for themselves. This was all on him.
