I just don’t think he’s the problem. He’s built a consistent top 5 team in the league. This just feels like a move done to appease a fanbase hungry for a championship for 5+ decades that wants to pile all that pressure onto a GM for 5 years.
Well, I can’t say with complete certainty that the problem is in him, without knowing what decisions he was responsible for. That is, it was Dubas who initiated the invitation of Tavares with such a contract, or the same Shanahan. It seems to me that Dubas' problem is that he gave such contracts to his stars and could not solve the problems of the defense and goalies, although this is very important in the playoffs. Also, his team looked constantly soft, which can also greatly affect the success of the playoffs. I don't want to dig deep into his trades, signings, and drafting right now, but there were miscalculations there too. Perhaps Dubas simply did not understand how to build a winning team and held on to his star players for too long, who twisted his hands with contracts.
I think he is still a very promising GM and this experience in Toronto can teach him a lot. If he's not a narrow-minded guy who thinks he's too cool and analyzes his mistakes in Toronto, then he can succeed in the NHL. I'm sure the demand in the NHL for it will definitely be.
