That view won't tell you anything without another angle.
It would also be reviewed, so I'm guessing Toronto saw it go in. It's possible they screwed up, but that view is just not conclusive.
Seriously? It clearly hits the crossbar and comes straight down outside the line. What are you watching? It didn't bounce of the back bar and the crossbar.
Clearly hits the camera in the net. The angle it comes down with pretty much confirms that.
Granlund is standing right in front of it and instantly has a natural goal scored reaction, so that tells me that from a different angle it had to have gone in.
Proves to me that it hit the post and the crossbar and doesn't cross the line. I really don't see anything questionable about it.
