Sometimes it comes back to basics, like who is good at throwing ball through the hoop. I think coaches can lose sight of that because they work on individual sets and plays etc during practice. They don't keep score in practice. Jevon has superior ability to Nigel in things that are likely to show up in practice. But Nigel can shoot and score. Teams have to defend us differently when he is in.
I will admit that I have been enamored with Jevon's quickness and defense. But he just can't shoot. And probably never will. I think we go with Nigel. Jevon can be our defense/injury guy when Nigel is cramping or throwing up.
