1st one - horrible angle. He got beat by that same shot 3 times this tournament. He overplays the short side and has half his body covering behind the net giving the shooters a ton to shoot at.
2nd one - he had the chance to freeze the puck, kicked out the rebound over and over, leading to the goal
3rd one - the shooter basically had 50% of the net to shoot at because Binnington for some reason panics and leans down
4th (should have been goal) - Binnington kicked out the rebound straight to Aho and scrambled. Lost the net, but Aho shot it wide on the open net
Also there were a few more chances where Finland had a ton of net to shoot at but kept missing the net. Binnington has terrible angles. On top of that he has zero rebound control. He kicks out every rebound and every chance is a scramble. How many times did Canadian forwards have to come back to get the rebound? Of course it's hard to do that when you're shorthanded - which is why it was chance after chance 6v5 - the other team has an extra player on the ice and you have a goalie who can't hold a puck. Only a matter of time until it goes in.
