Whether the whistle blew or not it would have made no difference on whether the puck was going in or not. No one was anywhere near being able to stop it. Backy also shot the puck BEFORE the whistle, but it crossed the line AS the whistle blew. The refs are extremely stupid! You can't possibly think they are that dumb. They must intentionally fuck things up on a regular basis so they can use the loosey goosey calls to sway games.
