- As of now, India are in a comfortable position but they shouldn't be complacent in the next home series against the Kiwis and look to strengthen their position. Last time they ran away with 1 draw test (because of bad light) when they were 9 down.
- Australia needs to win BGT against India, otherwise, they are in a tough situation because they have an away tour against SL and the Lankans are in some form.
- SL should do alright against Australia at home but they need to channel all their energy towards Proteas in an away series. They successfully won against SA in 2019 so one could hope for a tight competition.
- Proteas could be worthy candidates for the finals if they win against Bangbros in an away series. After that, they are playing 2 home series against SL and PAK.
However, I do agree with you about not underestimating them in the T20 format since it's a very unpredictable format. I still don't think India will lose the series, but it could be a lot more competitive as you mentioned.
Indian fans should enjoy it while it lasts because such streaks are meant to be broken. I would guess that once Ash-Jaddu takes retirement or some freaky fightback from any touring team (both are obvious guesses tho, no rocket science). I'd be a happy person if we cross the 20-21 mark, saying it because Aussie got 2 good runs and we should at least double it, anything above is a bonus.
