I can find people who don't know a damn thing about Ali or who he is...hell, I'd suspect the young generations of now won't know a damn thing about Ali especially with boxing's decline in popularity.
And sorry MachidaKarate, your family member isn't a good representation of the rest of the world. :P
I could care less about Ali or Fedor TBH. In a few weeks I'll never think twice about this strikeforce event but hey...it's a fresh and interesting topic right now.
