The New York Knicks are losing a key member of their front office, as senior vice president of basketball operations Gersson Rosas is leaving the organization after helping build the team’s championship roster.

According to a league source, Rosas’ contract expired and he has decided to pursue new opportunities. HoopsHype’s Michael Scotto first reported the departure.

Rosas joined the Knicks as a senior basketball consultant in February 2022 before being promoted to senior vice president in September 2023. He appeared to confirm his exit in an Instagram post featuring Knicks president Leon Rose and senior advisor William “Worldwide Wes” Wesley.

“Celebrating an NBA Championship and the successful completion of our New York chapter with FAMILIA,” Rosas wrote. “Fulfilling the vision of bringing a championship back to New York after 53 years is a legacy I’ll always be proud to have helped build. Being part of assembling a team that represented the city, connected with its fans, and brought people together was one of the most meaningful and cherished parts of this journey.

“All love to my Knicks family. The peaks and valleys, the sacrifices, and our relentless commitment to making this plan a reality made the achievement even sweeter. Grateful for every moment of this legendary milestone.

“Mission accomplished. On to the next chapter.”

Before arriving in New York, Rosas held front-office roles with the Houston Rockets, Dallas Mavericks and Minnesota Timberwolves, bringing years of executive experience to the Knicks during their championship-winning rebuild.
