In late May, news broke that Taylor Jenkins had made decisions on his Milwaukee Bucks coaching staff, retaining stalwart Darvin Ham while adding Patrick St. Andrews and Joe Boylan. However, that no longer appears to be the case, with Marc Stein reporting that Boylan will instead join new Mavericks head coach Dusty May in Dallas.

“After stints with five other NBA teams, including Memphis, Boylan was initially expected to reunite with Taylor Jenkins on his new Milwaukee staff. But I’m told Boylan is now Dallas-bound along with Willie Green,” Stein wrote, later adding that Boylan will coach the Mavs’ Summer League team. This has since been announced on the Mavericks’ official NBA.com page.

This is a disappointing outcome for the Bucks, with Boylan viewed as a perfect fit for a rebuilding Milwaukee team with plenty of young talent. Highly touted for his constraints-led approach (CLA) to coaching, Boylan seemed particularly ideal as a developmental coach for Nate Ament, Milwaukee’s 13th overall pick via the Miami Heat, given his success working with the Minnesota Timberwolves’ Jaden McDaniels, who followed a similar path to the NBA. Undoubtedly, Boylan would’ve been beneficial for the Bucks’ other prospects too, including 10th overall pick Brayden Burries, new acquisition Kasparas Jakučionis, the returning Ousmane Dieng, and the recently signed Bogoljub Marković.

Jenkins and the Bucks must now find a replacement for Boylan on the coaching staff. As it stands, Patrick St. Andrews will coach the Bucks’ California Classic Summer League team. For more on that, including roster details and scheduling, check out our Summer League primer.
