A big reason why Chennai Super Kings have been as successful as they have is that, over the years, little has changed in terms of personnel. That's not something you could say about the new champions of the Indian Premier League, the Kolkata Knight Riders. Bar their owners and some members of the management, the team has seen a complete overhaul in five crazy years. Everything that could be changed has been.
But change isn't KKR's most distinguishing feature. There is one thing that is so different about Kolkata that it could redefine Twenty20 cricket altogether if the team sustains its high performance level. This is a team that has been built on bowling, rather than its batting.
Twenty20 has often been viewed as packing the team with a posse of big-hitting batsmen, and filling up the rest of the spots with bowlers. If you look back, hardly any team has played more than one or two bowlers from the overseas pack in their squads; of the four foreigners available, three were usually batsmen.
