i think your expectations are a little too high. Most people didnt even to expect him to play in the NHL this season let alone start the season with the team. And then having him play at the level he is is just remarkable.
he ia a rookie, playing like a young vet. He ia going to have mistakes. That is fine. Even at this “lower” level of play, he is exceeding expectations.
personally is he plays at this “lower” level the rest of the season, i would still be ecstatic bc he is playing at a top 4 level. Which again is much quicker than anyone anticipated.
