I'd expect that the Sharks will actually cut those players that were involved if there was any genuinely serious breaches. According to my second hand sources since Barry Russell took over Cronulla has been determined to weed out and crush the behaviour that's brought them so much grief in recent years. I know the sentiment that Cronulla wasn't punished sufficiently for the drug saga from many years ago still lingers but the new guy can't unfuck that woman, so to speak. What he has apparently been doing is putting a new broom through (he did self report the current financial irregularities) and if his form holds he will come down heavily on any proven offenders.
I have no clue what happened other than what's in the media but as it happened publicly some time ago and hasn't been a big blowup till now it might be just a few lower graders getting pissed up and fighting amongst themselves and some senior players not bothered. No matter, I'm sure it will be reported on and we'll in due course learn more.
Like always I'll view it like any other indiscretion from any player or any club, that is I'll wait till I have the relevant facts and disregard the emotive media reporting before forming a view.
