I don't particularly like the idea myself, but given that I am not the ICC, my head is out of the sand and I can see it is inevitable now that something will happen. The other issue is where you play, the "North" has 3 international grounds, and London 2, so what happens? In the interest of spreading the game you move them around the region, therefore reducing the amount of 2020 cricket (which was intended to get people involved in cricket) to around 1/3 of what it was in each county? Going backwards slightly? Yes.

I would love to see them keep the county game, and if the regions must come into being, then have it as a "showpiece" type event of the best performing players in the domestic game. Then looking on the bright side, everyone will be in form, and for the first 8 weeks of the season everyone has to perform to be selected for their region.

Possibly try this as a blueprint
1. Players all remain contracted to existing county, but window for EPL agreed and all contracted players available. Now every side has about 50 eligible players to pick from.
2. EPL held in July (3 weeks?)
3. Regional squads picked on 20th June ish. Now players have approximately 2 months to put in sufficient performances in order to get selected.
4. Salary cap for selected squads in place, all players guaranteed minimum amount. Adds an actual incentive to play, rather than players being picked up with no significant reward.
5. Set number of overseas players permitted, limits on match squads ie 4 U25, 3 overseas.

That way it will be fairer, perform and you get more cash, and the intensity of domestic games should increase and hopefully players will get better as a result.

As for playing county games over 5 days, I'm not convinced theres enough good players to perform for that long. Most games which are not rain affected are over in just over 3 days as it is (although draws are getting more common).

There was another thread in which I suggested making domestic cricket 3 divisions of 6 (Premier, 1 North and 1 South) and then realigning minor county cricket to fit below this (ie north/south not east/west) I still see that as a better solution to the problem, as it will give a more structured entry for new players and make it easier for counties to recruit.
