Players who have reached their full playing potential

[LeeD]

Player potential....
Doesn't that need a covergence of physical skills, mental concentration, mental interest, avoidance of injuries, and a few other variables I didn't bother to think of?
Kinda like a graph, with lines running in all different directions, where the seemingly converge is the best the player will ever play, where they diverge meaning something is lacking in the overall player level.

[papertank]

Reached their potential: Nadal, Ferrer, Hewitt, Fish, Monaco, Simon, Davydenko, Tipsarevic

Definitely have not reached it: Murray, Monfils, Berdych, Soderling, Tsonga, Dolgopolov, Del Potro, Verdasco
