Unwritten laws don't exist
In the history of jurisprudence there has never been such a thing as an unwritten law. If it isn't written down in the finest legal jargon then it isn't on any statute book.
And if it doesn't exist then it stands to reason that an unwritten law can't be broken.
It is also a complete and utter falsehood to suggest that football players and managers do not comment on football clubs other than their own.
You could have been forgiven, after the events of the weekend, for thinking that Celtic's manager, Brendan Rodgers, had broken new, and clearly consecrated, ground by commenting on the internal affairs of Heart of Midlothian Football
Club by analysing the reasons why Ian Cathro had been an incomplete fit at Tynecastle and had become an unemployed manager as a consequence.
Rubbish.
Rodgers' comments were not, as Jon Daly had suggested in a hissy fit after Celtic's win over Hearts at the weekend, "Disgraceful," or "Disgusting."
Nor were the remarks "Very poor form" or "Farcical," as Daly had alleged in an uncharacteristic vowel movement.
It was faux outrage from the messenger boy who had, during the course of last season, been sent down from the Directors Box at Aberdeen to the Pittodrie dug-out with a note for Cathro penned by the fair hand of Hearts' Director of Football, Craig Levein.
That televised episode, along with the footage of Levein going into the away dressing room at half-time, encouraged the widely held belief that the running of team matters might have been, shall we say, a complex affair.
Rodgers alluded to that possibly being the case when he was asked to comment on Cathro's sacking prior to the first league game of the new season, against Celtic.
The manager exercised his right to freedom of expression and is now on the receiving end of a hostile backlash for his trouble.
But to suggest that managers and players do not comment on other clubs is nonsensical.
Derek McInnes said last season that, with the budget for players available to Pedro Caixinha at Ibrox, Rangers should have finished above his Aberdeen side and taken second place behind Celtic in the Premiership league table.
The comment was made after Caixinha had said that, in his estimation, Aberdeen were at the end of their cycle as the best of the rest outwith Celtic.
Earlier on, Caixinha had also alleged that McInnes had wanted his job at Rangers, implying, I would assume, that Derek was agreeable to the idea of getting out of Pittodrie.
So don't give me unwritten laws, managerial etiquette or any other manufactured case against Rodgers.
He speaks his mind, just like his managerial counterparts.
When Brendan was asked about the club ban on that disreputable group of Celtic fans known as the Green Brigade, imposed after the flaunting of paramilitary banners and including one that involved the identity theft of the manager's image, Rodgers did not hesitate.
He told the recalcitrants and the recidivists that Celtic Park was not a political chamber, it was a football stadium. And he reminded them that their psuedo-political posturing was not welcome inside it.
That was, once again, Rodgers accessing his right to free speech, for wehich he was applauded at the time.
The extent to which the manager's message has been received and understood will be able to be assessed when Astana go to Celtic Park for their Champions League qualifier next week.
But social media response to Rodgers' defence of the club's image suggests the hard of understanding are still of the belief they are bigger than the club
In the meantime, that's us then.
We've opened the season with a high profile spat between Rodgers and Daly.
We've had a wee square go at Paisley involving St Mirren's assistant manager and Falkirk's goalkeeping coach, which saw both sent off.
And the vastly experienced, but incorrigible, John Robertson lasted all of fourteen minutes before his first competitive match in charge of Inverness Caley Thistle, against Dundee United, saw him sent to the stand for dissent.
We might not have much money in Scottish football but you get a great laugh.
You wouldn't need a particularly vivid imagination, for instance, to visualise the high jinks when Neil Lennon takes Hibs to Ibrox at the weekend for the first meeting of the clubs since the Edinburgh side won the Scottish Cup final against Rangers in 2016.
The reaction of the home crowd when Neil appears in full view will be an assault on the senses, but that's allowed so long as everything stays peaceful.
And then Hearts go to Kilmarnock. Hang on, isn't that the place where Kris Boyd plays up front?
The same Kris Boyd who has a newspaper column in which he stated that Ian Cathro couldn't handle a dressing room full of experienced professionals.
The same Kris Boyd who wrote on the day of Cathro's sacking, "I hate to say I told you so, but I told you so!"
I thought no-one spoke about clubs other than their own?
Don't ask me to believe that fans of all clubs who hurl verbal abuse at players and managers with reckless abandon can believe it's disgusting, disgraceful, farcical or very poor form when a manager makes a considered judgement on the removal of a fellow member of his profession.
That, in my opinion, would be hypocrisy on the part of the fans if they did.
And there's no law against having an opinion. Unwritten or otherwise
