India discard Mohammed Kaif has sounded cautious about the much-debated multiple-captaincy theory for IPL T20 second edition proposed by John Buchanan, saying it looked "interesting".

"I don't want to say much on it except that it looks interesting as things happen quickly in the shortest format of the game. Not a bad theory, but we have to wait and see how it goes," Kaif told reporters last night before departing with his Rajasthan Royals teammates for South Africa.
