Monty Williams is thrilled to be at the helm of the NBA's best team after a 40th win of the season for the Phoenix Suns saw him rewarded with a coaching role for the upcoming All-Star Game.

The Suns became the first team this season to hit 40 wins as they overturned a 12-point fourth-quarter deficit to clinch their 10th straight win, beating the San Antonio Spurs 115-110.

Devin Booker top scored with 28 points including four three-pointers, while Mikal Bridges hit 26 and Chris Paul added 20 points, eight rebounds and a season-high 19 assists.

With his team the best in the Western Conference – and the league – Williams will now coach Team LeBron in next month's All-Star game.

"It's a huge blessing, to be in this position where you can be the caretaker of an organisation, represent an organisation, the city, the team, your family," Williams told a news conference.

"I'm mindful of that. I'm also mindful of all the sacrifices people make so I can be in this position. This is a team effort for sure. The players, what they do every day, our staff. The medical people.

"There's so many people that contribute to this. You get to coach the game but I'm thinking about everybody that has contributed. Our place is a special place, with a special group.

"I'm so grateful for the blessings that I have. God has blessed me beyond measure, in so many ways, to do what I do, get paid for it, live in Phoenix, drive the car I drive, have filtered water at home.

"I have so many things that I didn't have as a kid that I don't take for granted and this is another one."

Barring a surprising omission, Paul will join his coach in the 2022 All-Star Game.

Paul, an 11-time All-Star, has averaged 14.7 points, 4.3 rebounds and 10.2 assists across 48 games so far in 2021-22, with his tally in the latter category leading the NBA.

"I'm just happy for Monty, happy for our staff," he told reporters.

"Everybody contributes to it, that's just the way our staff is, everybody plays a role in it. It may seem like something small to a lot of people but that's big.

"Some coaches coach in this league for a long time and never get that opportunity. I'm glad that more people around the world get a chance to see him celebrate."

Asked about his players saying they were determined to win in order to secure his place as an All-Star coach, Williams said: "It blew me away.

"I wasn't almost in tears about it but when I sat and thought about those guys thinking about me in that way I was quite emotional because it's really my job to put them in a position to be successful.

"To have them want me, our staff, to be in that position, says a lot about them. It's a special group and I'm grateful to be part of this resurgence of basketball here."
