I'm 28, I think I have around 50 more years to live.
Will I, or any of us, ever experience someone greater than Djokovic/Federer/Nadal?
Next gen struggle to make a slam final. Winning slams is not as easy as Big3 made it look like.
There's a good possibility that whoever will be the greatest at the end of this era may be the greatest we will ever experience in our lives.
