Just 2:47 into the Utah/Houston game, Rudy Gobert was called for his second foul of the game. He gave James Harden a little push with his forearm (as many post players do when establishing position) and Harden flopped as he usually does when other players get near him.
Gobert, mad at this soft call, along with a highly questionable foul call on the tip-off, slapped something on the scores table (one of the chalk bottles?) into next week. This display of frustration earned him an ejection. Not (just) a technical foul.
