I think Lendl, Sampras, Connors, Laver, Rosewall, Agassi, Gonzales did reach their full potential. Connors might overdid it. Federer and Nadal are not done yet but with the way things are going, there is little doubt that they are reaching it too.
Bjorn Borg, McEnroe did not. They could do much better.
I don't know about Djokovic. His collapse is quite shocking and I don't know that's because his body has reached its limits or the problem lies deeply on his mind.
