We'll never know. Test series aren't just a test of your "perfect" team. They are a test of a nations cricket strength in every department- depth, coaching, strategy, leadership, versatility, mental strength, adaptability/learning. It's pathetic to claim otherwise. You go to war with the army you have, not the army you want.
ALL Test wins count. There is no "oh but, of this oh that". You win or you don't. India won, they were better. Bancroft can't crack the team now. Pattinson is no loss because he never plays- talented but will never put it together for long before he breaks down.
Warner is a big threat at home, Sharma & Bumrah's ability to tempt him around the wicket with those away swingers will be a real turning point for who wins. The ball won't swing for that long & he'll only miss a couple at most before he finds range. They NEED to get that right quick.
Smith has just recently shown a hint of mortality vs the short ball. It's a but like Bradman averaging 56 instead of 100+ during the Bodyline series but it is something... a chink in the armour.
I'll see how India do in the rest of this match & NZ tour before I assess chances in Oz.
