Inside the Mavericks front office, Mark Cubans shadow GM is causing a rift with Luka Doncic – The Athletic

In early February, during the second quarter of a home game against the Golden State Warriors, Luka Doncic carelessly turned over the ball and received feedback from a Dallas Mavericks employee he didn’t care for: Haralabos Voulgaris, a well-known sports gambler hired by team owner Mark Cuban in 2018.

Voulgaris, sitting with an open laptop in his typical courtside seat across from the Mavericks’ bench, motioned downward with his hands, which Doncic specifically interpreted as Voulgaris telling him to calm down, multiple team and league sources tell The Athletic. Doncic snapped back, telling Voulgaris, according to one source’s recollection, “Don’t fucking tell me to calm down.” The same sources say Voulgaris later professed that his motion wasn’t solely directed at Doncic, but regardless of intent, it only worsened an already inflamed relationship between the two.
