School spokesman Mike DeGeorge said Barrett plans to hire an agent but has not yet chosen one. The AP All-American averaged an Atlantic Coast Conference-best 22.6 points along with 7.6 rebounds while forming half of perhaps the nation's most potent one-two punch along with classmate and roommate Zion Williamson.
Barrett is widely projected as a lottery pick. The decision came as no surprise. After Barrett in February became the first Duke player since 2006 with a triple-double, coach Mike Krzyzewski said the ACC's leading scorer was only "going to be here a very short time."
He helped the Blue Devils earn a No. 1 ranking in the final AP Top 25 and claim the top overall seed in the NCAA Tournament. Duke was knocked out by Michigan State in the East Regional final. Barrett was Duke's most consistent scorer, scoring at least 13 points in every game with six 30-point performances. He had 33 twice — first in his college debut against Kentucky, and then in a home loss to North Carolina after Williamson left in the opening minute with a blown-out left sneaker and a right knee sprain.
Williamson and classmate Cam Reddish have not yet announced their plans for next season. Point guard Tre Jones said earlier this week that he would return for his sophomore year.
