Williamson became a viral sensation for his dunking displays in high school, then delivered in his lone collegiate season at Duke.
Williamson was the AP Player of the Year, Naismith Award victor and Wooden Award victor among his many accolades this season. Williamson formally revealed his intentions in an Instagram post.
He is a virtual lock to go first overall in June, but Blue Devils teammates R.J. Barrett and Cam Reddish declared earlier and are both in line to hear their names called within the first handful of picks.
The world finds out where Williamson will very likely start his National Basketball Association career on May 14 for the NBA's Draft Lottery.
And that it was, the 6-foot-7 forward averaging 22.6 points, 8.9 rebounds and 2.1 assists over 33 games that included an ACC Championship and NCAA tournament disappointment, with the Blue Devils bowing out to Michigan State in the Elite 8.
Now, all that needs to be determined is who exactly will be picking first overall. New York, Phoenix and Cleveland have the best odds of acquiring the number one pick, followed by Chicago and Atlanta.
