In addition to those awards, Williamson won the ACC Freshman and Player of the Year, the AP Player of the Year, the Naismith Award, and was a consensus First Team All-American.
Williamson became a viral sensation for his dunking displays in high school, then delivered in his lone collegiate season at Duke.
Williamson had one of the most-impressive freshman seasons in college basketball history, averaging more than 22 points, 8 rebounds and 2 assists per game for the Blue Devils.

But transition defense remained an issue for the Pacers as the Celtics outscored IN 24-14 on the fastbreak. IN then missed two more shots before Cory Joseph connected on two foul shots at the 5:27 mark.
Williamson hinted at his decision following Duke's 68-67 loss to Michigan State in the Elite Eight on March 31, saying that there was a high chance the Blue Devils' squad "will probably never play together again".
Williamson, who racked up several national player of the year awards during his lone season at Duke, is widely projected to be the No. 1 pick in the NBA Draft.
The NBA Draft Lottery is just less than a month away (May 14) and the draft will take place in June. New York, Phoenix and Cleveland have the best odds of acquiring the number one pick, followed by Chicago and Atlanta.
