For “bust” reference: Kakko has more NHL points than anyone from his draft except Jack Hughes while playing a fantastic defensive, possession and board game. And while playing for a team that didn’t often give him top line mates and power play time, which Hughes has benefitted from.
Lafreniere has the second most NHL points, and most goals, from his draft class while also learning a complete game. And of course the two scoring at a better clip (Stutzle, barely, and Raymond) have had plenty of top line and power play minutes, because they are on weak teams where they are given more prominent roles, which has not been the case for Laf.
Not worried.
