Every game has its own rules. They’re there for a reason - so that everyone works to a level playing field. That there’s no unfair advantage. So that there’s no bias in how one team or player is judged relative to another.
Of course, teams push the boundaries. They’ll operate at the margins of the rules where they can, in order to gain some sort of advantage. I get that.
But underlying it all, it’s important for everyone to operate on the basis of fairness and the principle of good faith performance. Surely, we all want that.
