"It's extremely exciting," Tatum said. "It's just another step closer to a lifelong dream that I've always had and it's the next step and I'm happy to be taking it."
This news isn’t a surprise, as Tatum is currently being projected as a top five pick in June’s 2017 NBA Draft, including No. 4 on Draft Express.
After missing the first eight games of the season due to injury, Tatum, a 6-foot-8 wing, became one of Duke’s most reliable scorers, averaging 16.8 points and 7.3 rebounds a game.
"I think it was a great season," Tatum said. "It started off a little rough, being injured and being a freshman and things like that, but towards the middle and end of the season I think I really grew as a player."
How did he grow?
"Just being more aggressive and just being a better scorer and being a better defender, rebounder and just hitting shots."
Tatum, 19, scored 20 or more points in seven of the 29 games he played in. Tatum was 45.2-percent from the field and hit 40 of his 117 three-point attempts on the season.
Tatum is expected to spend the summer working out with NBA skills trainer and owner of Pure Sweat Drew Hanlen. Tatum said he's going to focus on his whole game and his physical development.
"Going to the next level there's so much you have to work on physically," Tatum said. Phycically, everything, extending my shot and being more consistent."
