The 21-year-old Wizard was having none of Kelly Olynyk in Game 3, refusing to go quietly into the night after taking a hard screen from the 7-foot center.
During the second quarter, Oubre was on the wrong end of a vicious screen set by Olynyk that sent Oubre to the floor.
After Olynyk began arguing the call with referee Monty McCutchen, Oubre charged at Olynyk, shoving him in the upper body.
While Oubre was kicked out of Game 3, it's going to be hard to see him suspended for Game 4 because he didn't throw a punch. This moment was just the start to an intense game that would have two more ejections and a flurry of technical fouls.
