Bussi was in net for the skate, Kochetkov in the other net. Freddie wasn't on the ice.
I'm thinking that he was seriously injured by the hit to the head.
Dump and change, every time the canes dump to change. Vegas holds the puck and tries to make long passes to get an advantage off the change by keeping their players on a little longer.
It's not just the defense, it's bad changes. 100% bad changes on the majority of the breakaways. A few on bad defense but a lot of them are on bad changes.
