Well my T20 idea was 8 franchises, play each other twice, 2 games a week for 7 weeks. 2 games on a Tuesday night, 2 games on a Wednesday night for 1 round of fixtures, then the weekend round would have one game on a Friday night, one on Saturday afternoon, one game on Saturday night and one on Sunday afternoon.
All games would be broadcast on TV; and sold in 4 packages. The fixtures would rotate thus: Round 1 Games A & B would be Tuesday night, C& D on the Wednesday. Round 2 Game D would be Friday night, A would be Saturday afternoon, B would be Saturday night and C the Sunday game etc. The broadcasters would then bid for the rights to broadcast Game A, Game B etc, with the proviso that at least one of the packages must be sold to a company that broadcasts FTA. I'd also commit the FTA broadcaster to providing a weekly MOTD style round up show to be broadcast on Sunday evenings.
