Dubas has done just about everything possible, except buy this team luck. He's brought in goalies, improved the D, veteran leadership, physicality (maybe not quite enough), change assistant coaches, signed Euro free agents... what he hasn't done, is found a way to stop Tavares from getting injured, or found a way to stop Matthews from being unlucky with unsustainably low shooting percentage, and hitting posts and cross bars, and he hasn't found a way to stop Marner from underperforming when it counts the most. What he is responsible for, is finding the right coaching to fix the PP issues. He is responsible for finding the right people, to get into Marner's head, and bring his playoff potential, to what it can be. I'm not a Dubas fan boy, and really don't care who is the GM... but he's done a ton for the team, and the failure lies with the stars not performing when needed most. We failed this past playoffs, because Tavares got injured, Matthews shooting percentage dropped, and Marner didn't play as good as his regular season potential suggests... this is on the players..... They are young, and they get multiple chances... if they can't figure it out, eventually the team needs to get changed, but it's too soon for that, these players are too young.
The blame so far.. is the players, and the PP...
