The shorter the format, the less people participate as you always get 2-3 stars doing the batt/bowling/keeping so each team needs 2-3 make weights who are happy to do nothing. This type of person is getting rarer.
Just need to ensure all formats are catered for
Sat league system
Div 1-4 draw
Rest 45 win lose
Parallel system for casual players
2020 on Astro with retire at 30. Keeps it cheap, quick and ensures participation as more players per game get a gig and no player dominates.
Sunday’s
Run the same again or simply leave teams to have friendlies
This will mean every player can pick what suits and if players still don’t choose to play then we/ECB has to accept that maybe they just don’t want to play
I can tell you what works for the club I run, but other clubs may be different:
2 Saturday teams, both playing 40 over cricket. One decent standard, one less so. Everyone in both teams likes 40 overs on Saturdays and there is zero appetite for anything longer or shorter.
2 T20 teams that each play once a week, the better team plays midweek, about half the games are retire at 25, half aren't. (We prefer to play this but sometimes our oppo refuse). The 2nd team play a mixture of midweek and Sunday lunchtimes, all games are retire at 25 and about half the team are teenagers.
The idea being that kids move from the junior section into the 2nd T20 team, then they might choose to start playing Saturdays, or they might just keep playing T20s indefinitely.
it works for us, we're one of the only clubs that is growing in our county.
