He was a pushover in the Nylander negotiation when Nylander held out to Dec 1. Larkin, Pasta, and Ehlers good comparables, but he gave in and Nylander at the time did not merit to be paid more than any of the players mentioned, he then put up a 27 pt season off of that contract. That was the biggest Dubas mistake because it set the table for other team unfriendly contracts. You can also criticize him moving on Kadri, Hyman, Brown, Bozak, amongst many too numerous to list here, some that have gone on to cups or cup finals as valuable support players. Not to mention him trading high picks for Nick Foligno types. Or his fascination with acquiring subpar goalies. Lots to chose here, he was an awful GM in Toronto, and probably still is an awful GM/President. Don't respect him much, tried to an end around on another dummy Shanahan. Not a fan of backstabbers even if the one being backstabbed is the politician Shanahan who one can say is the architect of the Dubas charade as a NHL Exec.
