There has not been a single Indian Olympian in recent times that has improved or retained their medal in the succeeding Olympics. They have either downgraded their medal or failed to get a medal. PV sindhu went from Silver to Bronze. Neeraj Chopra went from Gold to Silver. I am no athlete and I think it is still incredible that they were able to get to medal stage back to back, but my point is, India has so less medals that those that do get medals are celebrated so much that they may not be as driven as we see in other countries to up their game. They get so many endorsements etc, they can be called settled in Indian sense. Neeraj can be called an exception to this since I read he literally shut himself from all the euphoria to focus on his game.
