I wasn't there, but if you look at it from the perspective of a sore loser, you can see why the Rimouski fans would be upset if they thought the Rockets rolled over for Windsor in their Tuesday round-robin meeting.
Because Kelowna "let" Windsor win on Tuesday, the Spitfires survived to eliminate Rimouski on Thursday and Drummondville on Friday. So I would guess that the twisted thinking of Oceanic and Voltigeur fans is that Kelowna is responsible for at least one of those QMJHL teams not being in the final yesterday.
My response would be that if the Oceanic or Voltigeurs want to play in the final, they should have done their own dirty work and beat Windsor themselves. They didn't.....too bad, so sad.
