Yes it would be a very disappointing season for him to be under a PPG. People predicting a 2 PPG season are out of their minds. Not a chance he was going to put up that many points as a 16 year old.
This is a different year now.. its a full season with more travelling and better rosters. I would say if he doesn't put up atleast 80 points and/or in top 10 of league scoring it's a disappointing season for him.
Sure even that is a big ask for a 16 year old but after seeing how his season was last year and just how good he is, I think it's somewhat expected from himself and from fans.
Hes off to a quiet start so far, but he will put up a massive game here soon and he will jump up within the league leaders soon
