Great memories of World Series Cricket every summer Australia plus 2 visiting nations each played each other 4 times 12 games plus best of 3 finalsVery hard to get around the Big Bash. Cricket is moving the way of "International Windows" like soccer IMO. There will have to be 2 or 3 protected 4-6 week windows through the year with T20s and Tests are condensed in. Not ideal, but if you want the best players representing their countries it will be the way forward.
14-15 games and full 50 overs and they still were able to fit either 5 tests vs one nation or 3 tests vs two nations .Wow that was a Summer of Cricket !
In tests and 50 over cricket batsmen had to both defend and attack so as not to lose 10 wickets too early but with T20 losing all 10 wickets unlikely so the skill sets are different in hit 6's and bowl very wide Yorkers.
International white ball (50 +20 overs ) is a 2 week Windows 4/11 to 18/11 Thats it !
