Zion Williamson is a "Shaquille O'Neal-type force" with skills like a point guard, according to Rick Carlisle, who saw his Dallas Mavericks struggle to contain the New Orleans Pelicans forward.

Having finished with a career-high 39 points in a loss to the Denver Nuggets in his previous outing, Williamson had 38 to help the Pelicans get back to winning ways on Saturday.

The 20-year-old contributed 10 points in a pivotal 18-8 run in the closing stages as he took over proceedings, helping New Orleans eventually prevail 112-103 as they claimed a third win in four outings.

Mavs coach Carlisle admitted his team found Williamson – who landed 12 free throws from 18 attempts, both season-high numbers – too much to handle with the game on the line.

"He's an unusual force and obviously a great player," Carlisle said.

"We'll have to figure something a little better out next time, but he's doing this to everybody. We did have some very good possessions guarding him, but he was a beast.

"It presents huge challenges for the defense and for officials. He is just creating collisions out there. This is a Shaquille O'Neal-type force of nature with a point guard skill set."

Williamson is averaging 26.3 points per game in his second season in the league, shooting 62.8 per cent from the field.

The first overall pick in the 2019 draft has had five games in this campaign with at least 15 field goals attempts and an 80 per cent success rate, the most by any NBA player since Charles Barkley had five in 1988-89 when playing for the Philadelphia 76ers.

Only two-time MVP Giannis Antetokounmpo (412) and Atlanta Hawks guard Trae Young (389) have taken more free throws than Williamson (364) so far this term, while he is also averaging seven rebounds per game.

His improvement as a playmaker is also impressive. Having averaged 2.1 assists in a rookie season that was limited to just 24 games, he is up at 3.5 through 43 outings in 2020-21, including 16 across in the last three for a Pelicans team fighting hard to make the playoffs.

However, while flattered by links to the legendary O'Neal, as well as other NBA greats, Williamson wants to leave his own legacy.

"I am who I am. I'm Zion. I'm trying to be the first and only Zion, that's all there is to it," he said after dazzling against Dallas.

The Pelicans are now 20-25 for the season to sit 12th in the Western Conference, with 14 of their victories coming in home games.
