Sources told ESPN that the frigid dynamic between Doncic’s camp — led by Lara Beth Seager, who became Doncic’s business manager after being introduced to him by Nowitzki — and Harrison and his new staff factored into the GM’s stunning decision to trade Doncic to the Los Angeles Lakers for Anthony Davis in February. Casey Smith, Jeremy Holsopple and Casey Spangler were all longtime Mavs employees who had helped Doncic, a Slovenian who spent his adolescence in Spain, make the major cultural transition after coming to Dallas as a teenager. They had become confidantes for the superstar, but sources said Harrison saw them as “enablers” of Doncic, despite them being immensely respected by their peers throughout the league. Holsopple was the NBA’s Strength and Conditioning Coach of the Year in 2021, and Smith’s tenure as Team USA’s head athletic trainer included the 2008 and 2012 Olympic gold medal runs. -via ESPN / April 21, 2025
