On December 7, 2007, Mavericks coach Avery Johnson and Nuggets coach George Karl had the honor of becoming the first pair of coaches to wear body microphones during NBA games.

Karl shouted at the beginning of the game: "Go and enjoy the game." Johnson also said during a timeout: "Man, good job, keep it up." After a timeout, Karl issued instructions : "Everyone must defend more seriously. Let's try to win by defense, not by shooting." At the end of the third quarter, the Mavericks trailed by 4 points. Johnson was still optimistic: "We must always maintain a high level. Intensity. I think we improved a lot in defending the ball-handlers, but a few players had to work harder in the last quarter to have a chance to win.

Listen, it’s nothing more than words of encouragement, and NBA coaches will also do some very shocking things during timeouts. For example, in the 2003 "Cow-Horse Battle", Nelson ran to argue with referee Crawford during a timeout. As a result, he received two technical fouls and was ejected. For another example, in the final stage of Game 3 of the Finals the year before last, Cavaliers coach Mike Brown called timeouts 18 times in a row, but neither the referee nor the players heard it.

Moreover, many NBA coaches like to swear at players during timeouts, so no one likes to wear a body microphone during nationally broadcast games so that the audience can hear what they say during timeouts. But because of the declining ratings, the TV giant proposed a "microphone agreement" when renewing its huge eight-year contract with the NBA, and of course the NBA could only compromise.

Phil Jackson compared this to surveillance, Riley said it would violate privacy, and Pistons coach Saunders was worried that the team's tactical layout would be leaked. George Karl asked: "Who wants to be stripped naked and put in front of the camera?"

NBA coaches can also criticize the "microphone protocol," but since the CBA began televising, coaches' speeches during timeouts have been The microphones were delivered to the audience's ears without reservation. These domestic coaches on the list probably did not expect that one day they would become the protagonists of funny quotes like Han Dazui.
