Surely they couldn’t let a five team Div 2 go ahead, either make a 13 team Div 1 and everyone plays each other once then rearrange the following divisions
I don't mind the idea of two larger divisions taking the place of the top three, where everyone plays each other once . Assuming Blacktown and HAC do indeed go down a division, this would leave 22 teams in the top three. Pushing Hunters Hill, St Pats and Newport (Who I believe are strong enough) into Div 1, and then combining the rest of Div 2&3 into one, would make two 11 team divisions.
The shorter, one round season would also be a drawcard in attracting players who don't want to commit to as long of a playing timeframe per year.
This would look like:
Div 1: Colleagues, Waves, Mosman, Drummoyne, Forest, Blue Mountains, Petersham, Knox, HH, St Pats, Newport
Div 2: UNSW, Epping, Lindfield, Hills, Barker, Old Iggies, Beecroft, Hawks Valley, Raptors, Briars, Harlequins
I suppose amongst that div 2 group it would be a massive issue making only three grades plus colts compulsory. With Halligans around there would still be opportunity for the excess players from clubs capable of fielding four + grades to get regular games, if they werent being used to bolster higher grades.
