It’s really up to India what they want to be known as. They are throwing around this narrative that this is the best Indian team ever (their delusional coach seems to think they are on par with the 80s WI and 2000s Aus teams!).
If you want to prove that and you find a way to back out of a Gabba test (whatever the reasons), then that says a lot about your ambition and the confidence (or lack of) of your team.
