Think this is an important step. Key going forward is not the format but rather not to isolate the non TMG counties. Bringing minor counties back into a competitive tournament would be great and far better than just having 8 franchises and everyone else twiddling thumbs. I do hope there's still room for a 50-over or 40-over comp though perhaps a knockout comp.
One option is to invite the National Counties (formerly the Minor Counties) to join the 18 first-class teams in an expanded competition aimed at providing promising cricketers with a pathway into the professional game.
The T20 Blast might then become a two-league affair, with promotion and relegation.
I know at least one member of this board won't necessarily agree but I do still think there would be merit in holding onto some of the new team names/identities going forwards. Birmingham Phoenix could still exist as a concept for mens and women's T20 as it has definitely broadened appeal within the Greater Birmingham/West Midlands conurbation/region. Ditto for the Manchester Wales and Southampton teams. Perhaps less a need to retain Oval, Trent and Northern however. They can go back to being Surrey Notts and Yorkshire. Warwickshire could potentially then even field a second string/academy side in division two of whatever emerges and play at smaller grounds under the Warwickshire umbrella as could Lancs in Liverpool etc...
