Why MS Dhoni gave up team captain role to Virat Kohli

Dhoni revealed that his decision was not impulsive but a well-thought-out one.

The Indian cricket team's most successful captain, Mahendra Singh Dhoni, shocked everyone when he announced his abdication from limited-overs captaincy. 
The news created uproar when the Team India captain made way for his successor, Virat Kohli, just ahead of the One-day Internationals (ODIs) and Twenty20 Internationals (T20I) against England in January 2017. On Thursday, Dhoni revealed that his decision was not impulsive but a well-thought-out one. 
"I resigned from captaincy because I wanted the new captain to get enough time for preparing the team before the ICC Cricket World Cup 2019," NDTV quoted the wicketkeeper-batsman as saying. "Selecting a strong team without giving the new captain appropriate time isn't possible. I believe that I left the captaincy at the right time," Dhoni told media in Ranchi recently.
Dhoni had given up the Test captaincy in December 2014 after the Melbourne Test. However, he stayed on as ODI and T20I captain after having taken on those roles in 2007. Dhoni led India to victory in the 2007 World T20 in South Africa, the 2011 World Cup in India, and the 2013 Champions Trophy in England.
Dhoni captained India in 199 ODIs, of which he won 110 and lost 74. He was captain in 72 T20Is, of which India won 41 and lost 28. He was also India's most successful Test captain, with 27 wins, 18 defeats and 15 draws. Dhoni is also the only captain to have led India to ODI and T20I series wins in Australia, and an ODI series win in New Zealand.
He went on to make 6,633 ODI runs as captain at an average of 54 and a strike rate of 86. As a captain in T20Is, Dhoni scored 1,112 runs at a strike rate of 122.60. In Test cricket, he made 3,454 runs at an average of 40.63.
