The third centurion was VVS Laxman who has the most elegant style of the four centurions because while watching all you can do is admire. Laxman's style is very exclusive to sub-continental batsmen as he is very 'wristy' and likes to deal in boundaries rather than quick singles. The fourth and the final centurion was captain marvellous MS Dhoni who has changed his style since he became captain and has an average of 73.45. When Dhoni started his career his style was similar to Sehwag but as he has matured he has started to realise and understand the scenarios of the matches he plays in. The innings he played in the match against SA was a brilliant knock that involved all of his unique styles as he started off slow and then picked up the pace.
All the four centuries were important to India winning this match in the end as they all played a vital role in different phases of the game. What I would like to get out of this post is that there is no perfect style, as long as the style suits the player that's the perfect style for him/her.
