Why the trio must leave?

Sachin,Dravid and Ganguly the "trimurthis" of Indian cricket has become more or less like a burden to the young generation. They are legends, they have made enough records that few can surpass, but the time has come the time or the age where arthritis catch one's feet faster than their reaction time on pitch, the time to call it a day.
The new generation has enough experience under their belt, enough experience to carry on their own. They have learnt a lot from them. But to move forward, the trio must be shown the exit door. I'd rather suggest them to retire in a high note than getting showed the door.
I'd rather suggest an example that I like on this matter. The example called the "Arsenal", where the Professor has the ultimate word. He didn't hesitate to sell Vieira or Henry, both the times critics said he club is doomed. But the Professor is always right. The first one paved the way for arguably one of the best midfielders in the world, the second one made the team gel even better now that they don't have to play the ball to TH14. The team are playing with a swagger that nobody could have ever expected. They are young, they are intelligent, they are confident more over they are Wenger's disciples. It is too early to comment on the outcome. But "In Arsene We Trust"
Back2India. Nobody expected young Indians to win the cup when they went to SA for T20 world cup, but they came as heroes, as the world champions. When the time comes even the Gods must call it a day.
