I like his idea of being flexible to convert games to day and night tough ..the extra cost for that should be bearableTo all intents and purposes, your "easily" includes having to buy millions of pounds worth of additional equipment, just for potential rain delays - and if that happens on the days there are two games, that's two lots of that millions of pounds worth of equipment you're talking about. This is before all the other staffing issues and so on.
It's also odd this idea that it only rains in England. Rainfull in June is less than many other countries during their cricket seasons.
