Hall of Fame
I feel like this is what will happen. These 3 players drive so much of the ratings and popularity in the game and all the tournaments around the world know that. Nadal was supposedly given a $1.5 million appearance fee to play in Washington. I suspect Federer and Djokovic have also been given equal or greater sums than that. When these 3 players eventually drop down the rankings, it feels like all the tournaments will bribe them with wildcards and huge appearance fees to desperately get them to keep playing. They might still be playing in their 50's or 60's. What do you think?
