Cricket clubs work best when they have a local community feel for me, a lot of which depends on facilities. Think a nice clubhouse and atmosphere plays a big part in attracting people to a club, particularly outside cities.
I'd bring in a rule that any club that pays domestic players won't get ECB funding. Overseas pros raising standards and helping with coaching etc, ok that can be a sensible move, but paying local players who'd be playing anyway doesn't make sense. Reinvest the money in facilities and cutting the cost of playing the game.
Get normal clubs and schools teaming up, and not just the big clubs. As many clubs with a good enough standard ground as possible should be in partnership with local schools who don't have their own pitches. Would make playing cricket easier for the schools and getting kids into youth teams easier for the clubs.
