Why Rahul Dravid is so precious to team?

Tweet

Compared to other players in Team India,Rahul is a team player and he performs in pressure situation.They are players in Indian Team who can't play in pressure situations and they also give up themselves when chasing a total.Rahul Dravid has improved his fitness and also raised his game over the years.At the end of the day,cricket is a team game and not a individual game like tennis.On the whole all the players should perform in order to win a match.In my opinion there is no other player than Rahul Dravid in Team India,who can withstand pressure and perform.Is anybody there who disclaims this facts or throw some more light on their viewpoints.
