Leadership function is all about vision, attitude, body language, ruthlessness and charisma.
Only Imran Khan, had it all.
There are born leaders, there are individuals who assume leadership in certain situations and crises and there are individuals on whom leadership is thrust due to seniority.
Imran is a born leader.
Saurav Ganguly assumed the mantle of leadership while Indian cricket was going thru a crisis after match-fixing and resounding defeats under Sachin Tendulkat.
Rahul Dravid became captain owing to his seniority, batting ability and his non controversial nature.
If Rahul Dravid knows that he does not enjoy the confidence of a group of cricketers within the team, he should either prevail upon the Selectors to drop them, whomsoever they may be and if the Selectors do not support or agree with him he should resign from the captaincy.
Somewhere down the line, Rahul Dravid the leader who declared the innings when Sachin was on 194 or the same Dravid who gave the ball to Murali Karthik ahead of Kumble and Hanbhajan (incidentally we won both the tests), that Dravid seems to have suppressed his individuality.
But he continues to captain for lack of an alternative.
