How many 16 year olds win futures these days, though?
Berankis did that, I think. I don't have time to google now
You can't compare different generations. There's a reason for why there are very few teenagers around, and a lot of veterans.
Cilic and del Potro are still very young, they just seem to be around for ages. And yes, I get that "the game got very physical".
But I still believe you can show some talent very early on.
Djordje started slowly. Maybe he'll get much better.
