WALTHAM, Mass. (AP) — Boston Celtics general manager Danny Ainge was approaching his postseason news conference when his cell phone rang.
He smiled and told reporters it was from his new coach, then ducked into the nearby workout room to take the call. But he was only half-joking: It was Doc Rivers calling, and he had just agreed to a five-year contract extension that would not only give him another run at a title with the current roster but keep him in Boston to help rebuild the franchise when the Big Three era is done.
“I think Doc is the best coach in the league. So it’s great for us,” Ainge said Friday at the team’s practice facility. “There’s nobody I’d rather have as my coach than Doc.”
Rivers contract was set to expire — he had an option for next season — and he said after the Celtics were eliminated by the Miami Heat on Wednesday night that he was “leaning heavily” toward coming back. But he was expected to return on a short-term deal to make one more run at a title with the Big Three of Kevin Garnett, Paul Pierce and Ray Allen.
Instead, the five-year contract worth a reported $35 million would give him the chance to lead the franchise with a rebuilt roster that probably won’t include any of the thirtysomething stars who led Boston to its 18th NBA title — and Rivers’ first — in 2008.
“Doc wants to be here. It’s not all because he thinks that over the next five years we will have the best team in the NBA,” Ainge said. “He’s part of this franchise. He wants to do what it takes for us to be successful.”
One year after Rivers waited into the summer to make up his mind to return for just one year, he decided quickly on a long-term deal. It was discussed in training camp, shelved during the season and then revisited after the first-round sweep over the New York Knicks in the playoffs gave them a chance to talk.
“He just wanted to come back this year and see how it was going to be,” Ainge said. “Doc has always known that we wanted him. That offer was on the table.”
Rivers has coached the Celtics for the past seven seasons, winning the NBA title in 2008 and reaching the finals in 2010 before losing in seven games to the Los Angeles Lakers. This year, Boston swept the New York Knicks in four games before losing to the Heat in the Eastern Conference semifinals in five games.
Ainge promised changes, refusing to even promise that the team’s four core players — the Big Three and point guard Rajon Rondo — would be back. If they are, there could be changes in the way they’re used, with an eye toward keeping the older stars fresh for the playoffs.
And the roster will be different, he said, acknowledging that the team got little help from the bench in the postseason — especially on offence.
“There were too many scoring droughts at crucial times in games,” Ainge said. “We need to improve our team to have a crack at it next year.”
—Ainge again defended the midseason trade that sent Kendrick Perkins to Oklahoma City for Nenad Krstic and Jeff Green. Neither of the players Boston got were productive in the playoffs, but Ainge said Krstic was recovering from bruises in both knees and Green might have needed more time to adjust to his role.
—Ainge said he would like to re-sign Glen “Big Baby” Davis, a free agent, but Davis has indicated he wants to go somewhere and be a star — or at least a starter.
— Jermaine O’Neal will have “pretty serious surgery” on broken bones in his left wrist, Ainge said, which could involved having pins or screws implanted. O’Neal, who is left-handed, was injured when he took a charge in the Knicks series and landed on his wrist.
—Ainge also said that he was waiting to hear from Shaquille O’Neal whether the future Hall of Famer wants to return. O’Neal played a total of just 18 minutes since Feb. 1, making just two, short appearances in the playoffs.
Ainge said O’Neal worked hard to get better, but he reinjured his right calf when he returned in the regular season. The team expected him to improve, but he never really did.
“I feel bad for Shaq,” Ainge said. “It was hard for me to watch.”
