This reminds me of a famous dialogue from the film Dangal where Aamir Khan aka Mahavir Singh Phogat said a very inspiring dialogue. If translated from Hindi, it means If you win a Silver medal, either tomorrow or the day after, people will forget you. But if you win the Gold, you will become a legend and legends are never forgotten.
That is the same case with Rahul Dravid and Sachin Tendulkar. We still remember Dravid because he was a pure gem! He is called ‘The Wall’ and was the most dependable batsman having faced the most number of balls in test cricket. But if you consider the most number of runs, Tendulkar outshines Dravid in both ODI and Test Cricket. Tendulkar even has the unique achievement of 100 centuries and makes him stand out from the crowd.
Even though that should not take away any credit from Dravid and his contributions not just to Indian cricket but to the country as a whole but Sachin will always remain Sachin. You might not remember how many centuries Dravid scored but you will always remember Tendulkar scored 100 centuries and had it been 101 or 99, you would have still remembered the number.
This is why Dravid said this and what he meant by this was two or three generations later, people will forget Dravid but they will always remember Sachin Tendulkar. It is the same reason why we will always remember the names of Neil Armstrong and Edwin Aldrin who were the first men on the Moon. But nobody remembers the names of the astronauts who next landed on the Moon. People always remember who comes first, not the one who wins the Silver.
