Tobias Harris pegs his Sixers “at the top’’ of the East, but the Long Island native believes the Nets are going to be there battling them.

Appearing at the NBA Players Association’s kids camp at Pier 36 Thursday, the Sixers’ standout small forward said he feels the addition of Al Horford and his own re-signing align Philly perfectly for big things.

The 27-year-old admitted to being hardly shocked Kyrie Irving and Kevin Durant are headed to Brooklyn, which battled Philly in an edgy first-round series.

The Nets had Harris on their radar if things fell through with KD. Harris indicated, too, he might have met with the Knicks if his Sixers’ five-year, $180 million deal hadn’t come to fruition so expediently.

“I wasn’t surprised,’’ Harris said of the Durant/Irving signings. “You heard a lot of rumblings before about it. I didn’t know for 100%, but if I had to make my guess, I would’ve said Kyrie and Kevin were going to the Nets. Kind of all season long you heard different rumblings. That would’ve been my educated guess.”

The Sixers lost to the eventual NBA champion Raptors in the second round. The Sixers lost Jimmy Butler this offseason, but Toronto lost its soul — Kawhi Leonard. Meanwhile, Harris, Ben Simmons, Joel Embiid and Horford make for a powerful foursome, and they also added Josh Richardson.

“I think for sure we’re going to be at the top of the East,’’ Harris said. “That being said, it’s hard to win games in the NBA. I know it’s going to take a lot of chemistry and work from every guy on the team. We have big goals for ourselves as a team. We’re ready for it.”

Durant may not make it back for the 2019-20 season following surgery to repair a ruptured Achilles tendon, but Harris saw enough of the Nets’ playoff fight in the five-game series to know they are for real.

“It’s great competition,’’ said the Dix Hills product who is training in Long Island all summer. “I love how the NBA is balanced. I love how everybody wants to go get their shot. I still think the East is quality, having a lot of great teams, too [like the West[. It will be a great year of basketball. It will be fun for the fans to watch.”

Maybe not for Knicks fans. The Knicks struck out on the big names in free agency and signed seven free agents — Julius Randle the most accomplished.

Harris said his father/agent had arranged meetings with other teams, but those never came to fruition because the Sixers’ deal got done. Harris referred to a potential Knicks’ meeting only as a “what-if.’’

Asked what he expects from the Knicks this season, Harris was dismissive.

“I don’t play for the Knicks,’’ he said. “I don’t care about the Knicks. I’m not going to waste my energy.”

Harris acknowledged the Nets “pulled their interest’’ once they got their two superstars and used all their cap space.

“Everything happened really fast at the start,’’ said Harris, an NBA community awards candidate who gave a speech to campers stressing academics. “A lot of moving parts happened. You got a good feel beforehand. It was a pretty epic free agency. I knew I wanted to stay, but you never what could happen in free agency.”
