Thats fine, a Stanley Cup is definitely worth celebrating with the players who won it, and it was a great playoffs for the Kings. I think every fan can find a way to send a message to ownership, and that includes you. You could make a difference by limiting future expenditures, particularly by spending less money on other NHL merchandise and products, and/or concessions at the arena.
My point was meant to suggest that we can still watch hockey and be involved with our teams but still send a message to the league. Thats a good middle ground for die hard hockey fans who are legitimately pissed but could never forego the game completely.
