We will see how many minutes he gets if he makes the team. He will play behind Beal and Monte. Maybe he gets a few minutes per game, some DNPCD's unless there is an injury.
He is a nice option if you have to have a three at the end of a game. Gillespe, Book, Beal, Allen, Durant, and even Bridges are all decent three point threats in special situations. All of those (except maybe Bridges) shoot with extreme confidence and would not shrink from taking the shot.
