Zion Williamson described his NBA debut as "a lot of fun" after he produced one of his customary dunks in the New Orleans Pelicans' preseason win over the Atlanta Hawks.

Williamson was on the floor for 28 minutes of the Pelicans' 133-109 victory in Atlanta, with the first pick in the 2019 NBA Draft scoring 16 points to go along with seven rebounds, three assists and three steals.

He also produced a moment which showed just why he is one of the most hyped prospects to enter the league, driving at Hawks center Damian Jones and bypassing his attempted block to finish with authority.

"It was a lot of fun," Williamson said afterwards.

"First NBA game – it's not going to count on the record – but it's the first one of hopefully many and I'm glad I can get that one under my belt."

Discussing his dunk on Jones, he added: "I just saw the lane open up and this isn't high school or college anymore, you've got to go up strong so I went up strong and I was able to finish."

However, Williamson was keen to stress he is so much more than just a player capable of producing highlight-worthy plays.

"I don't think just dunking would have got me here," he said.

"I had to be somewhat of a good basketball player to get here, so whenever I have a chance to showcase my other abilities I try."

While it appeared that Williamson was enjoying himself, he noted that he still has plenty to learn.

He was 0-for-2 on three-point attempts and was heckled by the crowd for missing a free-throw try, ending up 4-for-7 from the line.

"If it was up to me I'd probably be out there laughing and joking a lot more," Williamson admitted.

"But I'm a rookie, I’m trying to feel things out. If I feel like I can do a lot more laughing and playing, I'm going to do it. But for now I'm low-key."
