Golden State Warriors coach Steve Kerr is generally one of the calmer coaches in the NBA.
On Wednesday night, though, he was anything but.
Kerr was ejected late in the fourth quarter of their 129-107 loss to the Portland Trail Blazers at the Moda Center after screaming at an official and spiking his clipboard.
With just less than four minutes left in the game, Portland center Zach Collins caught a pass while cutting to the hoop. As he was going up for the shot, Draymond Green smacked Collins in the arm, causing the ball to go flying and picking up a foul.
That, after a review, was upgraded to a Flagrant I.
Kerr, clearly unhappy with the call, started screaming at the official. After slamming his clipboard on the ground, Kerr was assessed a technical foul. Seconds later, while still yelling at the official, Kerr was quickly handed his second technical foul, ejecting him from the game.
Kevin Durant eventually had to hold Kerr back and walk him off the floor, while he was still screaming at the official, before he left for the locker room.
Kerr said after the game that he was surprised the foul was even reviewed in the first place.
Kerr was then asked about the clipboard spike.
Portland, which held a seven-point lead before the ejection, quickly jumped to a 15-point lead after sinking all five free throws and a huge 3-pointer from Jake Layman on the next possession.
The Trail Blazers, clearly with the game under their control, finished on a massive 19-4 run to cruise to the 22-point win. Golden State, which scored just 12 total points in the final quarter, scored just twice after Kerr's ejection — clearly a turning point in a game that featured 22 lead changes and 16 ties.
Durant and Steph Curry each dropped 32 points for the Warriors in the loss. They were, however, the only two on the team to score in double figures.
Damian Lillard led Portland with 29 points and eight assists, shooting 9-of-15 from the field. Layman added 17 points off the bench, and CJ McCollum finished with 15 points.
