In recent games, Martin St-Louis has made some changes to his coaching style during matches. This was highlighted on L'Antichambre, where the coach started changing his lines during games for the first time. According to the panelists, it's a sign that he is gaining experience.
However, during the game against the Golden Knights, this did not happen, and there was a flurry of criticism, particularly regarding his management of certain forwards' ice time.
In defense of St-Louis, Josh Anderson may not be scoring, but that's the only thing he's not doing on the ice. He is very involved and useful nonetheless. However, the point that various analysts and fans are making is that St-Louis misjudges the ice time for players who are having a good night.
In summary, there's a lot of discussion, but it's important to remember that St-Louis is also in the early stages of his coaching career, learning the profession just like the players. He has made mistakes and will make more, but he will eventually adjust.
