On the field, Mahendra Singh Dhoni is as composed and unflappable as he is off it. But 'brute strength,"murderous form,' and 'a man possessed' were some of the phrases that came to mind when he became the first regular Indian keeper to score a one-day century on 5 April 2005 in Visakhapatnam. 'Mahi' Dhoni had transformed from a boy from an obscure small town to a sports legend with the aura of a rockstar with his striking form on the day, his long locks visible beneath his helmet, red tints glinting in the sunlight. Dhoni, however, was no child prodigy or overnight success. At the age of 23, he made his international debut.
