The Dallas Mavericks continue to make headlines with unpredictable moves, adding yet another twist to an already intriguing offseason. Just as the NBA franchise appeared to be settling ahead of the expected arrival of top prospect Cooper Flagg, the Mavericks are once again shaking things up—this time within head coach Jason Kidd’s staff. Assistant coach Sean Sweeney is on his way to join the San Antonio Spurs, led by rising star Victor Wembanyama.
According to NBA insider Shams Charania, Sweeney has reached an agreement to become the associate head coach under Mitch Johnson in San Antonio. “Dallas Mavericks assistant Sean Sweeney has agreed on a deal to become the associate head coach of the San Antonio Spurs under Mitch Johnson,” Charania reported, citing agent Andy Miller of Klutch Sports. “Sweeney has interviewed for coaching jobs in recent years and now departs the Mavs for an elevated role.”
Sweeney’s departure is more than just a typical staff move—it raises important questions about the Mavericks’ internal stability as they prepare to build around a new generation of talent. Cooper Flagg, widely projected to be a transformative player, will require a structured and consistent environment to thrive. This change in the coaching hierarchy adds a layer of uncertainty to how Dallas plans to manage its roster and player development moving forward.
Potential departure of Jason Kidd
Since Tom Thibodeau’s exit from the New York Knicks, speculation has swirled about who could take over as the franchise’s next head coach—and one prominent name in the mix is Jason Kidd. According to a report from Ian Begley, the Knicks are actively considering Kidd as a candidate to replace Thibodeau, who was dismissed following New York’s run to the Eastern Conference Finals.

Despite guiding the Knicks to their first NBA conference finals appearance in over two decades, Thibodeau was let go as the organization looks to chart a new course. New York was eliminated by the Indiana Pacers in six games.

“The door is not completely closed on the Knicks and Jason Kidd,” Begley reported, citing sources close to the Mavericks’ situation. “Other outlets reported as recently as last week that Kidd was still a possibility, and that remains the case as of Monday.” While no final decision has been made, the possibility remains open as the Knicks evaluate their options.
What’s next for the Mavericks?
The Dallas Mavericks are entering one of their most uncertain offseasons in recent memory. From the blockbuster departure of Luka Doncic to securing the No. 1 overall pick in the NBA Draft, all signs are pointing toward the arrival of top prospect Cooper Flagg. Add to that Kyrie Irving’s ACL injury and now the departure of lead assistant Sean Sweeney, and the Mavericks are navigating significant instability on multiple fronts.
While some expect chaos, others see an opportunity for a reset and potential surprises. With a generational talent like Flagg possibly joining the roster and front office changes in motion, Dallas could either spiral further—or emerge with a new identity heading into the 2025–26 season.
