India's journey post the 2015 World Cup can be analyzed into two distinct phases. After bowing out from the semi-finals of the 2015 World Cup, India under Dhoni proceeded to lose its first ever ODI series against Bangladesh (1-2), a home series against South Africa (2-3) and 1-4 in Australia in the 2015-16 season.

Part of India's problems during that period was a lack of potency in the fast-bowling department, with Bhuvi struggling with injuries and the likes of Mohit Sharma, Umesh Yadav being woefully inconsistent. Enters Jasprit Bumrah and since then India has managed to string together one of the most potent bowling pairs in contemporary white-ball cricket.

In the middle of the 2016-17 season, with Virat Kohli's astounding run-of-form, both as a leader in Test cricket started murmurs on him being graduated to lead in all formats of the game. Ahead of the impending 3-match ODI series against England in early January 2018, Dhoni shocked the world by relinquishing the captaincy duties to Kohli.

A 2-1 series win against England was followed by a Champions Trophy campaign, which saw the Men in Blue lose to Pakistan in the finals. The loss in the finals proved to be another flashpoint, as the duo of Ashwin (Average of 47.3 at a strike-rate of 50.6) and Jadeja (Average of 61.58 at a strike-rate of 67.5) were dropped in favour of two wrist-spinners in Kuldeep Yadav and Yuzvendra Chahal. Since then, India has defeated Windies (2-1), Sri Lanka (5-0 & 2-1), Australia (4-1) and South Africa (5-1).

So, what changed for India post-Champions Trophy? It was their spinners ability to pick wickets in the middle-overs, with Kuldeep (28 wickets at 20.77) and Chahal (34 wickets at 21.88) choking the batsman into submission.

Post 2015-World Cup, the Men in Blue have played 59 matches, winning 39 of them with a Win/Loss ratio of 2.05.
