welcome to the internet -- where it is very easy to document what happened, verified by trusted third parties and video.
1.
Georgiev gets in a physical altercation with DeAngelo
2.
Georgiev taps and yells at his own teammate for a screen.
Later apologized, admitting it was not right and a mistake.
3.
Georgiev says something to Rantanen and Rantanen explodes and cusses him out, on ice, during a game. Rantanen, Cup-winning Alternate Captain, saying "Shut the f*** up, you shut the f*** up, I'll f***ing kill you," in the middle of a game, is not a ringing endorsement of Georgiev's general attitude and whatever he said to Rantanen just before this.
There is one ingredient in all these interactions. DeAngelo is an asshole, but Rantanen is not known to be one, and the dumb petulant slash speaks for itself.
You can put your head in the sand because the guy's putting on a Sharks sweater for the next 5 months, be my guest, but I don't think it's necessary, and I'd save up your positivity for players that deserve it and matter to our future.
