1. Will never happen
2. No club does that -every club changes them every few years as a money making exercise.
3. We are already doing this a lot
4.Supposedly this is happening, but realistically we don't even have a game-plan at nrl level so of course the coaches at lower levels are adapting a game-plan to suit their players.
5. There is one NSW Cup team. Branded as Magpies but many NRL clubs use other club's brands at that level (Newtown, North Sydney, Blacktown, Mounties etc.)
So really we've already done most of what you say.
