Russell Westbrook drove to the basket, De'Aaron Fox took a swipe at the ball and appeared to have gotten Westbrook's face instead.
But no foul. Just a traveling violation. And a season of frustration boiled over.
Maybe frustration with the officiating, a league-wide issue this season. But maybe more frustration with this mystifying Thunder season.
Westbrook sprang to his feet, barked at referee Matt Boland, received two technical fouls and was ejected from the game.
But here's what Westbrook knows. No matter how bad a game the refs did or didn't call, it was no worse than the Thunder played.
