Tricky question. Last year I would have voted the Sens by far but with their 4,459,745 picks and prospects, they can't fall lower and reach the Earth's nucleus. Aside this, Melnyk remains the worst owner.
IMO Yzerman will build something decent in Detroit, he proved that in Tampa. So I would probably vote for the Devils: I don't see anything positive in this organisation.
I still put my joker for Montréal. Having Timmins still in place is beyond any logic, but Bergevin's
If the vote was for most toxic owner, I would create an alternate account and vote twice for the Senators, but since it's just for the worst organization in the NHL, I agree that it's the Devils. I have faith in Yzerman's ability to rebuild his team, and while Tom Fitzgerald's been an Assistant GM for a long time, he's still a rookie in the main job.
