Disclaimer: my thoughts are Dubas is a fraud and should have already been fired, frankly he never should have been hired.
Current Roster:
What he inherited: Matthews, Marner, Nylander, Reilly, Liligren, Woll
What Dubas has brought in around them:
Goalies:
Samsonov - made since to sign him to a 1 year "show me" contract. Dubas was lucky thathe was available (see Murray below).
Murray - has been terrible and injury prone for years. This was Dubas "big swing" to upgrade the goaltending from the previous year (ie: the god awful Mrazek signing he did)
Dubas brought in the #1 goalie who had a solid regular season, has been average at best during the playoffs. The other goalie who is once again injured is taking up valuable cap space that could have been allocated to another area.
Dubas grade = C (a decent to good starter on a 1 year deal, a below average starter who defaulted to backup goalie who is always injured and taking precious cap space).
Defense:
Schenn - finally went and got a physical stay at home dman that fans have known was required for years.
Brodie - had been solid up till this season, he lacks of offense was annoying but made up for that based on his strong dzone play - not this case this season!
McCabe - has been a solid addition, brings an element of physicality that was needed but is a better skater than the typical hard hitting stay at home dman - does not provide offense.
Giordano - has played his heart out since getting here but the years of hard miles are showing and he is better suited as a 7th Dman at this point.
Holl - has been a 7th Dman (quality of player) his entire NHL career that Dubas has constantly brought back and even protected during the expansion draft. While never a good player he got completely embarrassed this post season.
Gustafsson - offense minded Dman that is extremely weak defensively. Seemingly brought in to be a depth dman.
Not at all an impressive group that Dubas is responsible for bringing in. In all his time as the GM he hasn't acquired anyone close to being a #2 or #3 dman. Muzzin is the best he brought in (I viewed him as a #4 - a very good one but shouldn't be the best dman on his pairing).
Dubas grade = D (at best 2 dman who are #4s, #6 dman and 3 #7/depth dmen).
Forwards:
Tavares - a lot of people complain about this.....not me. You have a chance to add a Tavares in Free Agency you take it...screw hindsight, you do this every day of the week. I don't give Dubas any credit or fault for this signing, every GM would have done it, Tavares wanted to come home.
O'Reilly - at this point in his career he looks to be a #3 C - a very good #3 that does the small things that matter in a 7 game series.
Accari - a solid bottom 6 player who plays with grit, this has been needed for years.
Jarnkrok - a decent bottom 6 winger who can produce some offense when playing with the big boys. When played in the bottom 6 he is invisible and does not add a speed or physical element that would help complement the core.
Kampf - a decent 4th line C however he also does not bring a speed a physical element that would help complement the core.
Kerfoot - has played on every line and continues to never find a home because he doesn't bring a single element to the game that helps complement the core. Doesn't have the offensive skill set to play top 6 and once again - another bottom 6 player that brings no physical element.
Lafferty - a replacement level player that has speed but doesn't seem capable of being able to forecheck.
Knies - first Dubas drafted player that actually provides value to the group. Has looked strong in his NHL/playoff debut. Not sure how high offensive upside he has but brings elements to the game (strong forecheck and board battle ability) that compliments the core.
Bunting - at times has been effective in a top 6 role. Seems to be in the right spot now playing on the 3rd line with O'Reilly. Brings a gritty element (net front) that brings a dimension that the core forward group lacks.
Aston-Reese - at times has looked to be a valuable 4th line player who plays a grinding game, other times looks completely disinterested in doing the little things that makes a quality 4th line player. Hovers between 4th liner and replacement level player.
Simmonds - seemed obvious the game had passed him by during 2020 season with the Leafs. Dubas saw something no one else did a signed him to a 2 year contract extension after the 2020 season - provides no on-ice value to the Toronto Maple Leafs. Some fans try to justify him as a "good leader to have around the room".
He was gifted 3 top 6 forwards. In his time as the Leafs GM he acquired 1 top 6 forward and has mainly shuffled around deck chairs in the bottom 6. To his credit this is the best 3rd line he has assembled to date.
Dubas grade = D (#2C, #3C, 4 good bottom six forwards, 5 replacement level type of players).
It is baffling to me that people worry what will become of the Leafs if Dubas isn't around. He has failed to find anything resembling stability in net,, failed to find Reilly a good D partner on the first pair (luckily Schenn has surpassed expectations and filled the role so far in the post season) and has built nothing more than an average 2nd D pairing. Continue to have 2 holes on the wing in the top 6 while wasting a ton of assets/draft capital since he arrived.
