"Overrated" may be the most difficult word to pin down to one criterion.
Yes, even more difficult than "sick" or "cool" or "planking."
Athletes can be overrated for the money they earn, the family they come from, the team they play for, the competition they played against and so much more. So when a list of the 100 most overrated appears, everyone will have a different opinion of what is valued more.
Suggestions and additions are welcome, but just know that yelling and screaming will secure your place on the "Top 100 Insecure Fans" list. Since it's impossible to know every sport, fans' voices have already been used to get the list together, so don't think I'm not listening
With that, let's get going!
P.S. Do not use the "I didn't think so-and-so was even ranked!" Everyone is ranked in his or her sport's community. End o' story.
