The Philadelphia 76ers and star guard Ben Simmons have agreed to a $170 million, five-year contract extension, a person familiar with the situation told The Associated Press. The max deal is the latest big commitment by a team expected to make a serious push at its first NBA championship since 1983.

Simmons, 22, will make about $8.1 million this season, the last of his four-year rookie deal. His salary for the next season will jump to about $29.3 million and rise to nearly $39 million in 2024-25, according to the person who spoke to the AP on condition of anonymity Monday because the contract is not official.

The deal solidifies the 76ers' core for the next few seasons. All-Star Joel Embiid and Al Horford are under contract though 2023, Tobias Harris through 2024 and now Simmons through 2025. Horford got a $109 million, four-year deal and Embiid agreed last season to a $147 million, five-year deal.

Sixers general manager Elton Brand had until the middle of October to reach a max deal with Simmons but wasted little time in locking up another cornerstone player.

Simmons was the No. 1 overall draft pick in the 2016. He made his NBA debut in the 2017-18 season and was Rookie of the Year. He was an All-Star for the first time last season. He has averaged 16.4 points, 8.5 rebounds and 7.9 assists in his two seasons.

"I think I want to work on everything and continue to let my game grow," Simmons said at the end of the season. "I think the one thing I got a lot better at this season was leadership."

The Sixers were knocked out of the Eastern Conference semifinals for the second straight season.

Philadelphia is 101-58 in regular-season games when Simmons plays. He has had 22 triple-doubles in the last two seasons, tied for third most in the league with Denver's Nikola Jokic and trailing Oklahoma City's Russell Westbrook (59) and the Los Angeles Lakers' LeBron James (26).

Simmons also has had 80 double-doubles over the last two seasons.

But he missed all 11 3-point attempts his rookie season and was 0 for 6 last season, a combination of an awkward shooting form and a hesitancy to keep shooting shots he can't make. Defenses sagged on Simmons daring him to shoot because the speedy All-Star can't do much outside the paint.

"I don't think it's taking shots just to take them," Simmons said. "I think it's just being aggressive and doing my job. I don't think it's any certain shot. But when you give me the ball, I'm able to make plays."

Harris, who re-signed with the Sixers this summer on a $180 million, five-year contract, recently worked out with Simmons in Los Angeles and found him dedicated to improving his shot.

"Everybody was trying to figure out why I was guarding him at the 3-point line, but it was really because he hit two of them," Harris said. "When I dared him to shoot two of them, he hit two in a row. That's why I was there. He's made big improvements on his game. His jump shot is looking really good and he has the confidence to shoot."
