The San Antonio Spurs’ Gregg Popovich has a rep as a hothead, having been been ejected for technical fouls at least 19 times over his career, according to Sports Illustrated. Turns out running hot may run in the family. The longtime coach’s 5-year-old grandson picked up his first career technical foul this month after tackling an opposing player during a game of hoops. Word of the youngster’s trouble came during the Spurs’ pre-game press conference Saturday, ahead of a matchup against the Golden State Warriors.
