The coaching staff changed, but Posh Alexander’s feelings towards St. John’s didn’t.

The Queens school presented him with his first scholarship offer way back in eighth grade. It was the place he could see himself playing at the most, in front of family and friends in his city. Thursday night, that goal grew closer to a reality when the explosive point guard from Our Savior Lutheran in The Bronx and the New York Lightning announced his verbal commitment to St. John’s and new coach Mike Anderson.

“My dream was always to play in front of my mom and my dad, and my whole family,” he told The Post in a phone interview. “This was a great option for me.”

The 5-foot-11 Alexander, a four-star recruit according to 247Sports.com ranked 105th in the 2020 class, picked the Johnnies over Seton Hall, Pittsburgh, Dayton and Illinois. Shortly after Anderson and his staff took over, they made it clear Alexander was a priority, with assistant coach Van Macon taking a particularly active role.

Alexander twice visited St. John’s recently, first with his high school team and then his family. He was drawn to the family atmosphere the staff is creating and the close bond it’s developing with its players. Everything he saw and felt, he heard from soon-to-be St. John’s freshman Julian Champagnie, a fellow Brooklyn native and friend. How Anderson would personally meet with players daily and the interest everyone on staff was taking in the development of the members of the team.

“When I went on an unofficial visit, I felt it was a great place for me to be,” he said.

Alexander is the second local recruit Anderson has landed, following Champagnie of Bishop Loughlin High School. Alexander is hoping to help bring more with him. He’s recruiting other locals, including wing Kadary Richmond, who announced a final four of St. John’s, Seton Hall, UConn and Oregon on Wednesday.

“Hopefully he can be the linchpin of something great,” AAU coach Shandue McNeill said. “They made an instant connection with Posh and his family. They did a great job of recruiting him.”

Alexander returned to the court this spring with the Lightning after missing his high school season with a broken arm and in 22 games in the Nike EYBL circuit averaged 13.6 points, 5.3 assists and 3.4 rebounds per game. One college coach familiar with him said his strength is attacking the basket and labeled him an electric athlete adept at finishing at the rim against bigger defenders.

“He thrives in transition,” the coach said.

He seems like a perfect fit for Anderson’s up-tempo, pressing style, which endeared Alexander to the program.

“He showed me film. I love the way he coaches,” he said of Anderson. “He goes real hard on defense – that’s what I need.

“What I love to do is play defense and get my teammates involved.”
