The clips that show Dante Exum exploding toward the rim, finishing with a thunderous dunk or contorting his body as he flips in a layup, sure are impressive.

That much is clear.

Yet, the 6-foot-6 point guard from Australia is one of the biggest mysteries heading into next month's NBA draft.

Fans in the U.S. haven't seen much of him, unlike Kansas' Andrew Wiggins and Joel Embiid or Duke's Jabari Parker.

Exum arrived Wednesday in Chicago for the draft combine and had already met with Phoenix, Philadelphia and Detroit as of Thursday afternoon. He had four more meetings scheduled for later.

He says teams "have an idea of what I'm about," but haven't seen much video of him.
