On full possession of the ball by the team in black. The ball is knocked out of bounds at 28 on the shot clock (no reset). Ball knocked out of bounds by the defense at 19 (No reset). Defensive Foul at 5 on the shot clock. The clock is incorrectly set by the shot clock operator at 35, Center officials noticed the mistake and then corrected it to 20. The ball is legally touched by the defense, and the clock stops at 19 (after 20 resets). This was done correctly. Offense finally scores a basket. Several sequences where the crew could have gone so quick that they made a mistake on where the shot clock should be set.
