It's a bit of a contradictory statement from Marchessault. On the one hand, he says his team has no excuse for not winning, but on the other hand, he mentions that his team doesn't win because they always play good goalies. In my book, that sounds like an excuse, right?
It sounds like a statement of frustration, and that's legitimate. The Golden Knights are still considered among the favorites to win the Stanley Cup, but the Nevada team is not capable of reaching the next level. They haven't been able to reach the Stanley Cup Final again since their memorable run in their first season in 2017-2018.
Still, it's quite disappointing not to be able to give the opposing team a modicum of credit, especially since the Habs did a colossal job of silencing the Golden Knights' guns. Yes, Carey Price was smokin', but let's give a lot of credit to the whole team, because after all, hockey is a team sport.
