CHICAGO — Danny Ainge didn’t make the trip to the NBA’s draft combine, and while he’s doing just fine in his recovery from a mild heart attack, it’s clear from sources here that he’s going to need his energy.

The Celtics will have the option to undergo a major roster renovation – in part by choice and also by the decisions of others – and Ainge and his staff will need to make some very large decisions in short order. Austin Ainge told the Herald on Thursday that his father is very much looking forward to staying on the job.

The team still has no definitive word on the plans of Kyrie Irving, who left on a two-week vacation after the Celts were eliminated from the playoffs by Milwaukee last week.

Similarly, New Orleans is also waiting on a meeting with Anthony Davis, and Pelicans sources say that discussion is expected to take place within the next week. David Griffin, who took over the team’s basketball operations last month, is planning to pitch Davis on staying put after a season that saw AD ask for a trade and say that, if that request wasn’t accommodated, he would opt out and leave as an unrestricted free agent in 2020.

There have been reports that Davis hasn’t moved from that stance, and if such is the case, sources here told the Herald the Pelicans will reach out to the Celtics as the most obvious trade partner. The Celts may still not be sure about a deal because it’s not known yet what the Pels will want in return for the All-Star, but there seems to be a belief that they’d be able to work things out.

It’s also within the realm of possibility that another team could jump into the picture, but it’s hard to see the Lakers as one of those teams. New Orleans sources said the team “won’t be doing business” with that club, with the bitterness from the Lakers’ attempt to engineer a Davis deal during the season still seething within the Pelicans’ organization.

It’s still unknown how much Irving’s decision will impact the Davis proceedings, but the Celtics seem ready to make their bid for AD whether Kyrie stays or goes.

It’s fair to assume the club knows that if it can get Davis that it must surround him with the right players. Sources around the Pelicans and league have said all year that he needs to be tougher (the constant trips back to the trainer’s room during games were a concern), and it was pointed out that he played some of his best basketball when he had Rajon Rondo in his face to call him out as needed.

There are some big dominoes to fall for the Celtics, and they could be in motion very soon. Having made over the roster in two fairly significant modes over the last few years, it’s likely to be happening again.

And Ainge will be making the calls. There was some concern that he may even step aside after suffering a mild heart attack on April 30 in Milwaukee – this after a similar event 10 years ago – but Austin told the Herald there will be no change at the top of the Celtics basketball ops chart.

“You know what, he feels great,” said Austin, here at the combine in his role as the Celts’ director of player personnel. “His doctors say he’s got a great prognosis. It’s one of those issues that it’s scary in the moment, but they found it and fixed it, and he feels good.

“He’s doing great. He really is. He’s been back to pretty much life as normal. He’s been at the office. He’s been at a few draft workouts. He’s talked with Brad [Stevens]. He did exit interviews with the players. So pretty much life as normal.”

As for why his father skipped the trip here, Austin said, “We’re trying to get him to not do as much, but he’s still fighting us a little bit. He’s feeling a lot better and just decided not to come to this event.”

And no doubt there is much work for Danny Ainge and the Celtics to prepare for over the next several weeks.
