The dugout is not a lecture room during a game

‌
— Manager Kim Tae-hyoung's 3 years: What has changed in his leadership? On September 8, during the game between Lotte and NC, there was a distracting scene. Manager Kim Tae-hyoung called Park Se-woong to the dugout during the game to reprimand him. Watching that scene, I felt a sense of doubt. What exactly is he trying to achieve by calling a player aside to lecture them in the middle of a game? In our time, this was common. Managers would stand players up and scold them. Military-style culture, such as "attention" or "at ease," still lingered in the sports field. However, times have changed. Nowadays, even in elementary schools, it is difficult to coach players in such a manner. Moreover, Park Se-woong is not a young student-athlete. He is a pitcher who has thrown in the pros for a long time. And above all, the game was not even over.
Reprimanding during a game is not good feedback. What should be in a pitcher's mind during a game? The next inning, the next batter, the next pitch. So, what help does it provide a player to be called aside to be cautioned and reprimanded over a play that has already passed? I actually think the opposite is true. Instead of helping the player shift their focus to the next play, it may result in them adding one more thought—the fact that they were scolded by the manager.
Strong reprimands during a game can look more like a manager venting anger rather than coaching. The principles of in-game feedback in modern sports psychology do not teach one to publicly stand a player up and reprimand them with emotion. Feedback should be specific and concise, helping the player focus on the next action they can control. This doesn't mean you shouldn't point out mistakes. Instead of "Why did you do that?", it should be "Let's do this next time." You should not hold a player back with a past play but return them to the next play. That is in-game coaching.
A manager's emotions are not coaching. Looking at Manager Kim Tae-hyoung's demeanor during games, he often shows an angry expression. He mumbles while watching a player's play from the dugout, calls players over to talk during the game, and sometimes tries to correct a player's movement or form on the spot. I do not believe this is desirable in-game coaching either. A game is not the time to build form. A player must trust and execute the movements they have practiced countless times during training. If you make them conscious of various aspects of their form during a game, they will start thinking about movements that should be instinctive. When thoughts increase, movements can become stiff. You should teach during training.
During a game, you should trust. If there is a need to fix form, it should be done with sufficient time at the training ground. You must diagnose why the problem occurred, talk to the player, and then send them out to the next game after they have mastered it through repetitive training. A few words from the dugout during a game will not fix form. An angry face does not make a team stronger. A manager is in a position where they must exercise more emotional restraint than the players. If the manager gets excited just because a player made a mistake, the dugout becomes even heavier. A player does not suddenly focus just because a manager wears an angry expression. Shouting does not improve control, restore batting balance, or improve defensive judgment. Rather, the player may start walking on eggshells around the manager. The moment the thought "What if I make another mistake?" enters their mind, their play becomes constricted. You must not make a player play while looking at the manager's face. A player should play by looking at the ball, the situation, and the opponent.
What has changed in 3 years? What I find more regrettable is that these scenes were not accidental occurrences in a single game. Over the three years since Manager Kim Tae-hyoung took the helm at Lotte, similar scenes have been seen multiple times. Angry expressions, reprimands during games, coaching from the dugout, immediate intervention in player movements.... If so, we must now ask the manager himself a question. He constantly demands change from the players. He tells them to change their form, change their thinking, and change their play. Then, what has the manager changed over the last three years? Baseball has changed. Players have changed. Education has changed, and sports science and sports psychology have advanced. The role of a leader must also change. A method of suppressing players with authority and trying to move them through public reprimand cannot last long. A professional player is not someone on the bench to absorb a manager's emotions. What a manager should do is not show anger. It is to accurately diagnose the problem, suggest a solution, and enable the player to perform their abilities again. I do not think the basics of coaching are difficult. You teach during training.
You trust during a game.
When a mistake is made, you prepare them for the next play. Watching the scene where Park Se-woong was called aside on September 8, I thought about it again. The dugout is not a lecture room during a game. What a player needs is not the manager's angry face, but
a single word that allows them to throw the next pitch properly. This is feedback, and this is coaching.
