Almost anyone would consider Roger Federer to play tennis as if he were not human. He's already won three majors that I can think of. The question is will he ever live up to GREATNESS of a pro like Sampras, Connors, Borg, or Johnny Mac? He has the skills, but will stars like Roddick be a factor in stopping him. My opinion is that yes, this is possible. One might argue that he already has, but what does everyone else think.
