Disagree completely with your take on that. Far majority of Leaf fans don't prefer the Bruins to Canucks, or vice versa. It would be like the Leafs versus Bruins on your end, not sure who you'd prefer more, but you hate both, hard to pick one. Maybe the odd Canuck fan would prefer one, and another Canuck fan would prefer the other. Except none of us Leaf fans really get why Canuck fans and the rest of Western Canada are so insecure about the Leafs, outside of HF, no one in Toronto really has second thoughts about any of those teams- in fact, from my experience, they actively root for them.
Should mention that I think the Bruins were just the better team. It was a bit more physical than the Canucks were used to, but not enough to swing the series honestly. Especially when they just got thoroughly outplayed in game 7...they didn't deserve to win in the end.
