The question made me laugh.
It reminded me of the aprocryphal quote attributed to Winston Churchill:
Question: "If you weren't British, what nationality would you most like to be?'
Answer: "British."
I am not an Aussie fan - how could I be, I'm English - but I am a fan of several Aussie players.
Here's my summary:
1. The batting has actually barely developed. Labuschagne is a great gain, and his improvement is 100% down to his county stint with Glamorgan. But Smith and Warner have returned, only for glaring Achilles Heels to become obvious.
2. Tim Paine is an excellent wicketkeeper and stopgap captain, but he is the exact same age as Azhar Ali, and he is always one bad series away from permanent retirement.
3. Nathan Lyon is the same as ever, he hasn't improved a bit. He will always be a 30+ average spinner.
4. As I wrote in another thread, the first choice bowling attack is all from New South Wales, and even before Pakistan arrived it was clear that for some reason they were getting the ball to do things in the Sheffield Shield that it didn't do last year after the sandpaper scam was terminated.
I would summarise the situation as "Back to 2017".
And I would add that the white ball wheels have come off totally. I was in the crowd for the World Cup defeats to South Africa and then the massacre by England in the semi-final. This is the Aussie white ball team's lowest point since 1992.
