Welcome to the Liberty’s superteam era.

After a dramatic offseason in which the Liberty completed an ambitious blueprint by bringing three superstar targets to Brooklyn, they vaulted to status as WNBA co-favorites alongside the defending champion Las Vegas Aces.

Now, beginning with Friday night’s regular-season opener in Washington against the Mystics, they’re carrying the hopes of delivering the original WNBA franchise’s first championship — which would be New York City’s first pro basketball title in 50 years.

“To have those expectations, that means we’ve earned them, right?” Liberty general manager Jonathan Kolb said. “That’s from this offseason and we embrace those expectations, but we know what comes with them.”

The Liberty’s aggressive offseason tipped in January, when they acquired 2021 MVP Jonquel Jones in a blockbuster three-team trade.

Jones, a four-time All-Star forward, requested to be traded to New York with one year left on a two-year deal in Connecticut, where she had led two Sun teams to the finals, including last season.

The Liberty also added valuable forward Kayla Thornton from Dallas in the deal.

Then came the monumental signing of Breanna Stewart, the WNBA’s most sought-after free agent — perhaps the biggest free agent in the history of a league that only in recent years empowered players to choose their destinations — following a multi-year, cross-continental courtship.

Stewart, the 2018 MVP and a two-time champion with the Seattle Storm, previously met with the Liberty as a free agent before the 2022 season.

This time around, as a Liberty contingent led by co-owner Clara Wu Tsai flew to Istanbul for a meeting with Stewart, the 28–year-old all-world forward teased fans for weeks with emoji-filled tweets that hinted at her next career move.

Courtney Vandersloot, one of the top point guards in league history, topped off the Liberty’s coup by signing a few days after Stewart, as a package deal, after spending 12 seasons with the Chicago Sky, with whom she won a title in 2021.

Stewart and Vandersloot each took well south of their maximum salaries to fit under the salary cap with the Liberty — Stewart on a one-year deal, Vandersloot on a two-year deal.

They join the team’s most prominent holdover, 2020 No. 1 pick and 2022 All-Star guard Sabrina Ionescu, who this week agreed to a two-year contract extension to stay with the team through 2025.

“We have a very talented roster and now it’s just about how we can play together,” Stewart said. “And with the facilities and staff and everyone around us — everyone wants to be great. So, when you’re surrounded by greatness, it’s a lot easier for you to be like ‘All right, I’m gonna do my best today.’ ”

The battle lines already have been drawn between these new-look Liberty and the Aces, who had an eventful offseason of their own.

The Aces added the legendary Candace Parker on a bargain contract to a core that features two-time MVP A’ja Wilson, Kelsey Plum and Chelsea Gray.

They also were embroiled in a controversy over head coach Becky Hammon’s alleged bullying comments to former player Dearica Hamby.

The high expectations and Aces rivalry talk that marked the offseason have not been lost on the Liberty.

“Coming into this market, you already know you have a huge target on your back,” Stewart said. “But now because everyone is talking about all these narratives and the biggest free agency and whatever, people want to beat us the moment we walk in the gym.”

But it’s also befitting a megawatt roster that bears little resemblance to the Liberty teams that went 2-20 as recently as 2020 and were eliminated in the first round of the playoffs the past two years.

The Liberty have not made it to the second round since 2017, the semifinal round since 2015 and the WNBA Finals since 2002, the franchise’s fourth runner-up finish in the league’s first six years.

“We want to win,” said head coach Sandy Brondello, in her second year with the team. “We’ve got all these great players. Winning a championship, that’s the ultimate goal. But … we don’t win championships in the preseason. We don’t win them in the start of the season, we win them at the end.”
