I'm sure there'll be more discussion about limiting Test cricket outside the Big 3 nations after this series. However are the likes of PAK, SL, WI, and BD faring much better in the white-ball formats ?
Instead of further narrowing the scope of international cricket, shouldn't we look to revive the weaker nations to see more competitive and compelling bilateral series ?
ICC would go some way to achieve this by doing the following:
1) Introduce cost-saving and cost-sharing measures so poorer boards can limit the losses of hosting series. Why must teams always stay in 5* hotels ?
2) Sanctions boards guilty of political interference.
3) Create a committee that specifically oversees cricket infrastructure, and set aside funds (only if boards meet good governance criteria) for improvement. There's massive variance in facilities between the richer and poorer nations. For instance, Dwayne Bravo recently said the Queens Park Oval ground in Trinidad hasn't changed since the 90s. Even a B stadium in India has better practice wickets, changing areas etc.
4) Introduce windows for T20 leagues to ensure the best players can both remain available as much as reasonably possible for national duty and also support their incomes by playing for franchises.
Otherwise we're headed down a road where cricket T20 franchises like football clubs will be the primary master of players who will occasionally be released to their countries with internationals having zero relevance outside tournaments.
