Jalen Brunson opens up on losing Julius Randle, Donte DiVincenzo

In the trade that has elevated expectations around the Knicks — along with their depth concerns — Jalen Brunson lost his good friend, former college roommate and honored wedding guest.

“[Donte DiVincenzo] was a groomsman at my wedding, so that should tell you everything you need to know about our relationship,” Brunson said. “I love him to death, and we’ll see him soon.”

DiVincenzo was “pumped” about playing for the Knicks next season and being teammates again with Mikal Bridges, a source close to the guard told The Post.

That runs counter to reports of DiVincenzo desiring a relocation because he was unhappy with the idea of coming off the bench.

Still, Leon Rose packaged DiVincenzo with Julius Randle to acquire Karl-Anthony Towns from the Timberwolves, a move that overhauled the rotation after last season’s run to the East’s second seed.

“Growing up with a dad [Rick Brunson] who was on nine unguaranteed contracts and played in eight different cities or whatever, you quickly know that it’s a business,” Brunson said. “And yeah, it’s not fun at all to lose those two like that, but I wish them nothing but the best and know that those guys are my brothers for real.”

Although he played just one season with the Knicks, DiVincenzo developed into a fan favorite and knocked down arguably the franchise’s biggest playoff shot since the ’90s — the Game 2 winner over the Sixers in the opening round.

A little over two months later, the Knicks acquired Bridges in a trade with the Nets.

The move likely sent DiVincenzo, the starting two-guard for the second half of last season, back to a reserve role.

“It all would have worked out,” Bridges said. “The main goal is to win. I think that’s the biggest thing is to try to be out there, produce and win games.”

Instead, the Knicks sacrificed the guard depth to acquire Towns.

After Brunson and Bridges, the Knicks guards now are Miles McBride, Tyler Kolek and Cam Payne.

Despite his status as the team’s best player and captain, Brunson said he had no input into the trade.

“I don’t deal with anything front office-wise,” Brunson said. “Maybe in the future, down the line. But that’s not my role. I gotta do my role, perfect my role, be the best teammate I can be.”

DiVincenzo’s popularity rose quickly and was pretty constant from the Knicks fan base.

That tends to happen when the player is on a high-value contract and the team is winning.

But DiVincenzo was only with the Knicks for a season, whereas Randle just completed his fifth campaign while earning his third All-Star selection.

Just two days before the trade was leaked, Randle was being honored at the groundbreaking of a new high school in the South Bronx, a ceremony attended by the Knicks front office.

Randle was lauded in a speech by Thibodeau and abruptly shipped to Minnesota, leaving behind a complicated legacy that included three great seasons and two bad ones.

“It was probably pretty difficult and pretty frustrating,” Josh Hart said. “[Randle] came here when the Knicks had a losing record, when they were struggling and he helped turn the franchise around and kinda change the trajectory of it.

“I think the organization and the fan base is eternally grateful to him for that. And the time that he’s spent here, I think — and you guys know he played with extreme passion, competitiveness. So probably tough for him, but I hope and know that the Garden is gonna show both those guys love for the sacrifices that they made.”
