So you think AO SF 2020 Fed > USO F 2005 Agassi?I swear sometimes you think age literally equals form. Like there is nothing else to consider except how old you are. Also, I made no statements about at all just asked a question. Who moved better physicall hampered ancient Fed or Agassi in 05? And as @Red Rick so astutely pointed out the answer is the same as if you asked who's serving better.
