Gregg Popovich isn't afraid to speak his mind to referees.
The San Antonio Spurs coach was ejected late in the first half of Monday night's game against the Minnesota Timberwolves for contesting a non-call on LaMarcus Aldridge.
Youtube user Hal Peter posted footage of Pop as he charged up the baseline and onto the court instructing the ref to "Blow your goddamn whistle, will you? Blow your goddamn whistle."
