Adelaide 36ers coach Mike Wells says an explosive NBL championship series is attracting more attention than ever in the US as the league's global standing continues to grow.

The Sixers take on the Sydney Kings in Sunday's title decider at a sold-out Qudos Bank Arena, with American-born stars Bryce Cotton and Kendric Davis the central figures.

Cotton and Davis have forged a fierce rivalry, which has intensified since the Kings' point-guard took exception to the Sixers' linchpin edging him out for the MVP award this season.

Their battles on and off the court have been one of the most tantalising storylines to watch throughout the season.

American imports Zylan Cheatham, Nick Rakocevic and John Jenkins have also played roles in Adelaide's title push, with Torrey Craig and Tim Soares adding further international flavour to Sydney's roster.

It's a recipe former NBA assistant coach Wells believes is having a huge impact for the NBL, alongside the successful Next Stars program for developing NBA draft prospects.

"The NBL is a global brand and a lot of people in the (United) States and in the NBA are aware of what's going on over here," Wells said.

"My phone's been quite full ... I think there's a lot of people that know what's going on because of this league and what Bryce and Kendric have done.

"You'll see an influx of players and talent, and there will be some kickbacks from this type of rivalry."

Cotton's bombshell move from the Perth Wildcats has transformed the Sixers this season, with the team now one win away from ending a 24-year title drought.

"We've had a hell of a year. We're proud to represent South Australia and Adelaide," Wells said.

"Getting Bryce was a big deal, but we've got a team behind him that is connected and committed, and I think people like the way we play.

"We probably play a little too much NBA-style for some people here ... but people are aware of what we're doing and how it's going.

"It's really exciting and I appreciate all the messages."

Wells controversially replaced South Australian basketball icon Scott Ninnis as Sixers coach in August 2024 and has worked hard to win over local fans.

His team has played in front of sold-out crowds all season and he hopes a Sixers title would bring South Australia together.

"Everybody's coming up and they know who I am now, maybe for the right reasons, finally," Wells said.

"They're backing our team and they're really involved in basketball."
