India skipper Rohit Sharma on Tuesday vindicated Jasprit Bumrah's promotion as the vice-captain for the three-match IND vs NZ Test series, terming the lead pacer as an integral part of the leadership group who has a lot of 'understanding' of the game.

Bumrah's elevation to vice-captaincy for the IND vs NZ Test series, beginning on Wednesday, came as a bit of surprise as India did not have a deputy to Rohit in the recent series against Bangladesh.
