The most mysterious story in next month's NBA draft isn't whether the Boston Celtics try to trade the No. 1 overall pick or take Washington's Markelle Fultz. It's not a story about how one of the most loaded drafts of the one-and-done era will turn out in the NBA, or about whether this will end up as the deepest point guard draft of all time, with Fultz, UCLA's Lonzo Ball, Kentucky's De'Aaron Fox and N.C. State's Dennis Smith poised to become stars.

The most mysterious draft story is this: Will the team that chooses Duke freshman Harry Giles -- somewhere middle to late in the first round, I would imagine -- turn out to be geniuses? Or will they turn out to have wasted one of the most important assets in the NBA with a first-round pick that went up in flames?

This is because Giles, a once-captivating young talent who suffered two torn ACL injuries before his 18th birthday, is the biggest risk-reward pick in an NBA draft since the Philadelphia 76ers picked Kansas' Joel Embiid with the third pick in 2014.

On one hand, the idea of drafting a near-Embiid-level talent in the middle of the first round is something that'll make NBA teams drool. Take, for example, one of Embiid's best games as a pro, in a close January loss to Houston. The big man scored 32 points, just shy of a career high, made 4 of 6 3-pointers, pulled down seven rebounds and added two blocks, three steals and four assists. There aren't many seven-footers in NBA history capable of performances like that.
