The timeline remains vague, distant, uncertain. Kevin Durant may not play this season.

It is the expectation Sean Marks set this week. It is the plan Durant allowed the general manager to offer the public, as the 30-year-old rehabs from a ruptured Achilles tendon suffered during the NBA Finals.

The Nets can be patient. The former MVP’s impact has already been felt.

“His presence when he walks into a room, when he walks into this facility … it’s a different vibe,” coach Kenny Atkinson said. “That presence changes things. It’s a different aura.”

And it’s a different era in Brooklyn, where the scrappy upstarts who broke a four-year playoff drought have transformed into the next NBA superteam, established when Durant and fellow free agents Kyrie Irving and DeAndre Jordan joined forces on June 30. That new era was unveiled Friday during Media Day at the HSS Training Center.

The three friends, who won Olympic gold together in 2016, had discussed the possibility of playing together over the past few years, but each player claimed the final decision to sign with Brooklyn didn’t happen until an early morning conversation on free agency’s first day.

“I think the reality of it didn’t set in until mid or late June,” Irving said. “We just had to be honest with each other, and 4:16 the morning, we still had no idea what we were doing.”

The trio then decided where they would spend the next few years of their lives, as casually as choosing a breakfast spot.

“We were just like, ‘You wanna do it?’ And everybody was like, ‘Yeah.’ It was that simple,” Durant said. “I’m trying to think of something deeper, but it was really that simple.”

Briefly, Durant said he imagined what it would be like to sign with another team, like the Knicks.

“I thought about it for a couple seconds, and see how my life would look in all of those places for a minute,” Durant said. “But ultimately I wanted to be here.”

Which meant Durant didn’t want to return to Golden State, where he signed three years ago, where the two-time Finals MVP became recognized as the world’s greatest player, where the forward could have extended an all-time dynasty.

“I felt like it was time for a change. I wanted to play for a new team and simply put, I just did it,” Durant said. “I didn’t really think about what I was leaving behind or what we accomplished. I put that up on the shelf already, and when it was time to make a decision on my future, I thought solely about me.”

Durant spoke of his new team’s culture, the up-and-coming supporting cast and his respect for Atkinson, whom he researched via YouTube clips. A Maryland native, Durant was excited to return to the East Coast, to play with his friends, to enhance his brand.

“Being in a big city like this will do nothing but help me. I looked at that as well,” Durant said. “I deserve a good city. I’ve been in the league for 12 years, and I make a decision like this, of course I’m [considering] the city.”

Durant was seen dribbling Friday, sporting a black No. 7 Brooklyn jersey in a surreal visual. Irving is in no rush to see his best friend wear it again on the court.

“There isn’t going to be any pressure from any of us at any time, and I will make sure of that,” Irving said. “We’ll be fine. We have expectations for our team, we obviously know [he’s] an integral part, but we’ll wait for that. I’ll be over-patient with Kevin.”

Durant’s return date ultimately comes down to one person.

“I make my own decisions,” Durant said.

And the aura follows.
