I think it’s slightly different these days compared to 50yrs ago, the amount of players from the pacific islands has increased and their IQ isn’t quite up to modern day scratch. Cricket, soccer and AFL don’t have a lot of these types in their games. These guys are big and bulky not suited to the sports I listed
The above might come across slightly discrimatory towards those nations but it’s a factor I believe.
Yes I know there’s a few Anglo Saxon types also getting in trouble but the % is probably no different than other sports.
