Yeah, that's not what the rule says. Rule says leave the vicinity of the bench, which he clearly did.
“During an altercation, all players not participating in the game must remain in the immediate vicinity of their bench. Violators will be suspended, without pay, for a minimum of one game and fined up to $50,000.”
1. It has to be during an altercation, which started after he was already on the floor.
2. They player has to be in the vicinity of the bench, which Love clearly was.
No suspension is the right call in that situation.
