While his progression has been simply phenomenal this year, Juraj Slafkovsky has been making headlines for the wrong reasons in recent days.
Indeed, the young Slovak is undisciplined, but he doesn't help himself by putting himself in the spotlight. According to Jonathan Bernier, "he needs to learn to shut up."
"Progressing and developing in the NHL isn't just about improving your skating, gaining confidence, making quicker decisions, and refining your defensive game; it's also about learning to shut up.
That's the realization Juraj Slafkovsky has had in recent games. [...]"
"I probably talk too much to the referees. That's probably part of the problem. I need to be nicer when I get a penalty. I shouldn't shout so much." - Juraj Slafkovsky
It's certain that word gets around among the referees. When a player starts to get a reputation for always complaining to them, he inevitably attracts negativity. The referees will also be on his case, and they won't miss anything.
The moral of the story is that he needs to learn to manage his emotions and gain experience before criticizing them. It doesn't have the same meaning for officials if, for example, David Savard talks to them compared to when Slaf does. He has to wait until he has a certain notoriety.
