Bergevin would actually be a really good as GM for the Leafs.
He deeply understands to win you need character, heart, size, etc, it cannot be done on skill alone. This is the one thing Dubas didn't seem to get or at least didn't do enough.
He's never really lost a trade except for Drouin-Sergachev.
Bergevin came on near the draft in 2012 so I am looking at 2013-20 drafts
Notable players from drafts -
2013 - McCarron, Lehkonen
2014 - Evans
2015 - Juulsen
2016 - Sergachev and Mete
2017 - Poehling, Fleury
2018 - Kotkaniemi, Romanov, Harris
2019 - Caufield Harvey-Pinard
2020 - Guhle

Montreal development and drafting staff sucked and this was actually really eye opening to see his transactions.
