Legend?

As you might know, the picture on the right is that of Royce Gracie brutally applying an armbar. When it comes to legends it's impossible to deny his status. Winning in impressive fashion against bigger stronger opponents and setting the standard for all MMA fighters to come. His name is legendary throughout martial arts everywhere.
Although some well known fighters are known as legends and it is undeniable, there are some that just don't fit the bill. I'm just going to touch base on what makes a legend, an actual legend. Please feel free to chime in with your legends list or a list of those called legends but really don't deserve the moniker.

What makes a legend anyway? Is it amount of fghts fought i.e. Jeremy Horn and Shonie Carter? Or is it an impeccable record no matter who they've fought? Do you have to beat a legend to be a legend? I'm so confused. Does one legendary fight make you a legend(Kongo vs Barry comes to mind). Well in my humble opinion winning belts in different weight classes should put you in that category for sure(Pacquaio and Mayweather, Henderson and Penn). Anyone moving up and down in weight and still being effective is surely a name that should be considered in the debate. Also the quality of opponents is a huge factor in deciding who's a true legend. I mean really, I gotta know some of these guys names.

I'm not sure what the criteria are for legendary status but I am sure that it is not an easy road to get there. As far as i'm concerned there is one factor that is nonconforming when it comes to making a case for being a legend and that factor is the fans. We decide the value of the fighters based on an endless list of ideas and reasons. Not only are we a factor in determining legends but we are always right.
