Get real mate. The adult comps are for the players who like their footy, but either weren't good enough to be graded, or enjoyed the social side of things too much and didn't want the strict discipline that comes with being a professional rugby league player. Hence the kids grades are the important ones as that is where the next generation of NRL players is going to come from, not the local A grade competition.
Also my mistake is not in the detail as I outlined what in fact has happened for about the last 25 odd years in the Parramatta District Junior Rugby League. There are some A grade games played on Saturday nights, but again, that depends on ground availability more often than not.
Changing the men's game to Saturday's so they can go out and get pissed? Please, get a grip
