From India's part, the batting was somewhat OK. It was their bowling which resulted in the defeat. First and foremost, the decision to drop Ravichandran Ashwin was a big blunder. I understand that Shardul Thakur is a better allrounder, but given how Jadeja troubled the Australian batsmen, one more spinner in the squad would have been very helpful. Ashwin could have been included in the place of Umesh Yadav, or even in exchange for another batsman. The last time India won an ICC championship was back in 2013. The long wait continues....
In the first inning, bowling was bad but batting was worse from the top order, most of them got an okay start but failed to continue for a long, our lower order came to rescue to some extent.
In the second inning, bowlers did a fairly good job and batters did show intent but again failed to convert their good starts to big innings, it happened with all the top 5. Literally, everyone got a good start and they were looking really good.
Apart from the batsmen, the majority of the blame goes to management because our bowlers did look tired. Umesh was completely out of touch, he didn't go through his usual runup when bowling, i believe he wasn't 100% fit.
