So how do you determine top 2?
Let's assume Eng, Ind, Aus, Pak, NZ, SL, Bang, SA, WI as 9 teams.
A round robin, where all teams play each other home and away for 1 test.
So that would be 72 test matches, with some nutty logistics worked in. 72 * 5 days = 360 days of play. And everybody plays everybody
360 days of play can be managed over 3.5 years to then culminate in the Final. Or even top 4 into a semi, and then a 3 series final (multi location for each test)
That could replace all the current bi-lateral series that mean nothing. In this instance every test match feed into a greater cup. Teams get rewarded for winning games and final league position. I think it could generate some very good global TV deals, so generate more monies than current.
It becomes a 4 yearly endeavour. Could work. Would be amazing!
