NBL champion Shane Heal has lauded the Sydney Kings' recruitment of Andrew Bogut while championship-winning coach Brendan Joyce labelled it the biggest signing in the league's history.

Bogut has confirmed the move on Twitter, but the Andrew Gaze-coach club is yet to finalise the full details of the NBA championship-winning centre's recruitment.

The Kings tweeted on Monday they were waiting on NBL head office to process the deal.

In line with player contracting procedures, the Sydney Kings have submitted to NBL head office appropriate paperwork for @andrewbogut for review and processing. The Kings will make no further comment but will provide an update in due course — Sydney Kings (@SydneyKings) April 23, 2018

Heal and Joyce told Fox Sports the signing was a coup for the NBL.

"Everyone thought they (the Kings) were asleep and then bang," Heal said.

"There's no doubt he can still play in the NBA ... Bogut will be the glue; he'll dominate this league not just statistically but in a way where he'll make his team better.

"This is an endorsement for where NBL's at, at the moment."

Joyce also believes the 33-year-old will make a massive impact on the NBL.

"(He's) one of the most intelligent big men I've ever been around," he said.

"We talk about talent and we talk about (basketball) IQ and he's off the charts in that area.

"Bogut will be able to score but I rate him one of our greatest passers, up there with (Luc) Longley as a big man and that's a big reason why Golden State wanted him.

"I'm sure there's going to be plenty of NBA teams wanting him so this is an unbelievable signing for the Kings, which benefits the NBL."
