Technically yes, but presumably any individual ref would be disciplined for not following procedure if they went off on their own. You need the PGMOL to state clearly and unequivically what the new guidelines are regarding dissent, and for it to be enforced without exception from then on.
That would then filter down to the grass roots level. Rugby refs don't get abuse even there, from what I've heard.
You used to be everything to me
Now you're tired of fighting
It is a funny one because for years - decades really - this has been an issue in the game.
And there have been repeated proclamations that they're going to get tough on this sort of thing and then they just...don't.
No-one seems to have the balls to send off 4 players in a game until the idiots learn to behave themselves. The culture of abuse of refs is so ingrained in the game.
