Kohli should not be playing T20Is at all. He should be conserved for Tests, and efforts should be made to ensure he doesn't suffer a slump in whites. Let Rohit Sharma and Raina stick to T20Is, as neither have a chance of cementing their places in the Test side. Taking a cue out of these specialist T20I captains, they can have someone like a Yusuf Pathan or Rohit Sharma or Pragyan Ojha (fair, that's a long shot) as a T20I captain.

Twenty20 used to be boring.
