re: Who is the worlds greatest athlete?

SFP, I think Soph already covered it.

I really do not know if there is a good answer to this question. The theoretically best way would be to take every athlete ever at their athletic peaks and have them perform sort of a physical fitness test. This test would basically see who is the strongest, fastest, best jumper, etc. Of course, the best total combined score would be the best athlete. I would venture to guess the answer would be a decathlete or Randy Moss.
