Isaiah Thomas never has been one to be shy about his own abilities, but as he looks around the landscape of the Eastern Conference, and sees what the Celtics have done this offseason, he doesn’t want to get too far ahead of himself.

The Celtics guard sees the additions of Gordon Hayward and Jayson Tatum to a team that was the East’s No. 1 seed last season. He knows something is going on in Cleveland, the team’s biggest road block to the NBA Finals, but he doesn’t want to put much stock into it.

Thomas is optimistic, but he’s cautious.

“We never put a ceiling on what we want to do,” Thomas told the Herald yesterday at Boston University, where he hosted more than 400 campers on the first day of his annual basketball clinic. “The ultimate goal is to win a championship, and that’s the only goal. So, whatever we have to do to try to get to the Finals, and try to get a championship, is what we’re going to do. We definitely have a really good team. We know that, the world knows that, and we just have to back it up.”

Part of blocking out any noise that will come with heightened expectations this season may include ignoring what’s going on in Cleveland. Rumors of dysfunction — amplified by reports that Kyrie Irving wants out — could put the Celtics in a more comfortable spot for conference supremacy.

But Thomas isn’t fueling that fire.

“I don’t really want to comment on that, I don’t know what’s going on over there,” he said. “I know just as much as everybody else knows. If (Irving) leaves, he leaves. If he doesn’t, then we know how good of a team they are, and we know how good of a player he is.”

Instead, Thomas is keeping to himself this offseason. He was off the court and shut down from basketball activity due to an injured hip since early in the Eastern Conference finals. His recovery from the lingering injury is progressing nicely and he said he should be ready by the start of training camp.

He opted not to have surgery, so he’s been resting for two-plus months. He recently got back in the gym as he tries to get into shape for the season.

“The hip is great,” said Thomas, who didn’t seem bothered by it as he played with campers yesterday. “It’s a real slow rehab process, but it’s getting better and that’s what it’s all about.”

Thomas’ health is of the utmost importance as the Celtics try to ascend the next step up the NBA hierarchy, and he personally looks to climb on the pay scale. He has one year remaining on his contract. He hasn’t been shy about his desire to land a max contract next summer.

Team goals and winning a title come first, but Thomas still expects a big payday. The two may come hand in hand.

“Very confident,” Thomas said when asked how confident he is that he’ll get that max deal. “I deserve it. I put the work in, and you can put me down against any guard in the NBA. . . . My numbers are up there with the best players in the world, and my team is winning. So, I mean, you have to reward that.

“I’m just going to keep working though. My time is gonna come. I have a lot of faith in God, and I just have to keep working to get better.”
