One "underwhelming" season doesn't equal to bust. For all we know we could be tearing it up with McDavid next season. A player rarely is ready for the league at D+1 so lets not pass judgement too early. I remember well when Laine tore his knee, couldn't skate the next season and people were like, doh, wasted talent. Now look at where he is. These are just kids, some take less time and some more. Jesse will adapt and find his game. With these tools it'd be crazy if he didn't.
How was his season underwhelming? He put up solid numbers as one of the youngest players in the AHL! Multiple first overall picks have vastly hurt people's perspective on prospect development, put into perpspective like other number 4 OV picks, if he was in CHL he would have tore that league apart
