Talk to Indiana Pacers coach Frank Vogel away from the court and you’ll find him to be calm—almost subdued.

But that all changes if you put him on the sidelines and add an NBA official to the equation. Vogel leads all coaches in technical fouls with nine on the season. He didn’t believe it, either.

“Do I really?” Vogel asked, according to The Indianapolis Star.

His most visible moment of outrage came in the Pacers’ comeback win over the Cleveland Cavaliers. With his team down big, Vogel exploded and received two technicals to be ejected from the game. The Pacers went on to erase a 20-point deficit.
