Matthews appears to be living up to his hype but the season remains young and teams adjust.  And the intensity of the playoff drive is yet to come which will also affect how teams play in general and against him in particular.  He has passed his first test...but more are on the way for the young rookie.

I think it is likely that he passes the upcoming tests and will morph into a bonafide elite star of the league but it is by no means a certainty.  Nonetheless, it has been fun to watch his progression to date as well as the other rookie Leafs in Marner, Nylander, Zaitsev et al.
