He's a funny guy. Tennis is getting good again with the old guard fading away aside from Djockovic, who is still on a tear and is solidifying his position as the GOAT. Nadal and Federer are gone. Raffa already announced his retirement and Federer just keeps delaying making his retirement official because, I'm guessing so he can keep his lucrative contracts with the likes of Gillette and Rolex.
There are a lot of young names in the mix though and I think we are going to see a changing of the guard very soon.
