For the other known players that have done crazy things too, they're just fined. They've probably got metrics on who's going to be suspended and who's going to be just fined.
Anyway, that really made Murray pissed when he's guarded and doubled by the Timberwolves. They know how weak he is mentally and sure Finch will do the same tactic on their next meeting.
And unless the player really push the button of the NBA, they won't simply put heavy penalties for the superstars in the league. Murray doesn't have history of being dirty though and perhaps that is also taken into account.
But I do agree, it players how has precedent already like Draymond Green, not just hefty fines, he could even be suspended even if it is playoff time. So we can say that NBA are someone favoring certain players and it's very obvious in the case of Jamal Murray here.
