Biggest thing to note - it's so early in the season and all players are humans. They go through ups/downs in their career and anything from slow starts to fast starts. It's a little bit of adversity and the guy will probably work through it.
But from an outside perspective, he's brutal. Everything he was doing well is not happening and he's playing awful hockey. It's so noticeable from just casually watching a game. But even the greats go through it. It's life of a professional athlete.
Be patient and make an analysis at the end of the year.
