Exum is the most mysterious and unproven projected top-5 pick in this year's draft. The potential is definitely there, as Exum is a 6-6, long-armed point guard who averaged 17.2 and 18.2 points a game in back-to-back years at the FIBA World Championships. But what worries you is his youth and the lack of talent he's faced. At only 18 years old, the Australian product didn't opt to play a year in NCAA despite offers from programs such as Georgetown and Indiana. The 76ers already have budding star Michael Carter-Williams at point guard, but it appears they're still interested in Exum. They could either trade Carter-Williams or put the two long-armed, explosive guards on the floor together.
