It's kind of strange how Generals Live is so sure that Kressler opened the door to do that on purpose when the video shows the door was open and 2 67s skaters going towards the bench.
I'm not sure I agree that this is some malicious act by a player with no real history of stuff like this.
It's possible that door had been opened from the last player coming off the ice that used it, (could have been half the team for all we know)
It looked like he is getting ready to close the door when it all happens.
These doors quite often are not latched on purpose.
Quite the far fetched tail to assume this is some planned act to hurt Rasmus.
