When I think of the word "legacy" I'm thinking what the general consensus will be 10-20 years down the line.
That being said, I think some people are being too analytical when it comes to the term. What makes Ali "The greatest" is not his statistics. It was his career as a whole. From the talk, to the fights. And that's why Conor is so important to Jose's.
It's not just Conor's credentials, whatever you may think of them, but it's the energy he brings with him. There's no one on this site that can honestly say there has been a bigger, consistent, uproar over a single fighter in the past 5 years. To the point where he's highlighted the division as a whole and has fans divided on such solid stances.
Add in the fact that you are the lone-standing champion of your division and more than likely the best mma practioner in the world who was seen glimpses of peril, but has managed to champion through all of it still.
This is totally different from Andy, GSP, or Bones. I think the thing that makes Aldo so great is that he's appeared human, but just has that much more than all of his opponents do. The reason why this is the most important fight for his legacy to date isn't because of how good Conor is or isn't, it's the entire momentum of the fight itself. Guaranteed when the promo gets heavy for this fight, you'll start feeling like you're about to be apart of something and THATS what legacy is. Remembering exactly what happened during this entire moment.
