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.ĭoncic, multiple league sources say, intends to sign the supermax extension - which he will be eligible for once named to this season’s All-NBA team - with Dallas, worth more than $200 million over five seasons after his rookie contract expires next summer. 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.
