So with 100% certainty, this is the difference.
With Eugene, he wanted to be in the know for everything, and would weigh in and make requests. This was true for Hockey Operations to marketing to communications, etc. Add in hiring Pierre McGuire to essentially spy on Dorion, and add his 2 cents, and you ended up with some really bad moves last year.
Without Eugene, Dorion has been told his budget is X. Beyond that he is free to make the moves he needs to. Same with other parts of the organization.
Ultimately, Dorion is going to have to live and die by his own sword, but he won’t have anyone else to blame this time around.
