Hi Ray...definitely worth a debate.
From my viewpoint all changes to the county structure seem centred around the franchise and it being not allowed to fail. This could see the start of the counties being merged eventually for all formats in time. Then play it all in a condensed summer like some club cricket...eg end April to end August.
A closed shop of scrapping relegation would be awful, as would applying to be one of the so-called elite for a finite initial time...eg 1, 2 or 3 years. It might not come to pass if a Yorkshire come down and be marooned in the lower cc tier.
16 cc matches would be fairer or revert to one division with fixtures alternated. Win that and you're true champions. The ODC should be better, agreed. Domestic t20 would need to revert to 3 groups of 6 with 5 matches then standalone semis and played in 3 weeks as precursor to the franchise. The domestic final on same day as franchise opener in same venue. As if handing over the baton.
This would then create window for ODC to run alongside cc in a league of one or divisions the same as cc. Or have a 3 team group then knockout ODC with some Minor Counties instead, thus replicating the World Cup. Each fc county then guaranteed a home match.
With so many blank weekends where there is no fc cricket no reason why the county game can't continue meaningfully when the franchise is on by continuing with cc fixtures.
