Dante Exum is facing a new challenge. The Utah Jazz guard has started the NBA season in a unique role, one that has forced him away from the basketball at the offensive end of the floor. Prior to Tuesday’s game against the Philadelphia 76ers, Exum has been partnered with either George Hill or Shelvin Mack every minute he has played. Hill is the Jazz’s big acquisition and the obvious starting point guard. However, when Hill rests, it is Mack, not Exum, who is receiving minutes as the Jazz backup point guard.
