India were probably overconfident. Australia played very well, and clearly deserved the win, but really, all their batsman bar Steve Smith struggled. I know Starc did okay with the bat, but he's not really a proper batsman like the others that have failed. The 2nd test is the most important test of the series for both sides. Don't forget, England drew the 1st test, and everyone praised them, but since that test, they badly lose the rest of the matches. If Australia can win or draw the 2nd test then it shows something serious. I'm actually not that surprised they won that 1st test because I remember that tour they had to Sri Lanka last year, and though they lost the test series 3-0, they actually performed really well in all those games, and could've quite easily won that series 3-0 themselves. We all remember how competitive that series actually was. Herath was the difference between the 2 sides in the end, and you could say he's the better spinner over Ashwin in tests. The Indian batsman were probably too casual against their spinners because its so hard to score of Starc and Hazlewood. But India need to perform a lot-lot better but you can't really blame them because they have been playing so much test Cricket lately. Probably fatigued show. It's important some of the reserves of the Indian squad get a game. India are also making the mistake of not including a leg spinner in their XI. The are one of the few nations they have a cluster of quality leg spinners.
