Woj reported this, so try refuting that!!

EDIT: It makes sense. Took this off his NBA.com bio page:
Bret Brielmaier was named an assistant coach for the Cleveland Cavaliers in July 2013. He joins the Cavs after spending the previous four seasons with the San Antonio Spurs, most recently as the team’s video coordinator.
The Mankato, Minnesota native is a graduate of the University of Arizona (’08). Brielmaier played on the Wildcats basketball team four years while at Arizona. He received his first glimpse into coaching during the 2008-09 season, as the team’s undergraduate assistant coach.
The 27-year-old’s first NBA experience came in 2009-10 as the Spurs player development assistant before being promoted to video coordinator for the 2010-11 season.
