Respectfully disagree.
Australia‘s approach at that time was generally only good for 230-240 in a 50 over game. You can’t even win 50 over cricket like that any more let alone T20.
Your suggested approach assumes that can pick off 5 singles and hit a boundary each over at will. It ignores wickets, good balls, mis-hits, good fielding, etc. It just isn’t realistic to achieve this.
I have no doubt T20 tactics will evolve but doubt they revert back to this type of approach.
lol
Simpson took over , what 30 years ago
Think 220 was considered a good score back then in a 50 over game.
Then it got to to 300 and beyond.
I guess everyone was thinking 400 would be the norm now.
Will never be realistic (achievable) if they never even try to change their thinking though ?
Every team wants to play the same way , game after game.
I guess the new tactic is trying to hit 3 boundaries a over.
So 3 x 4 = 12
12 x 20 = 240
Remind me when T20 teams are scoring close to this consistently.
