Not everyone knows who Roy Jones Jr. is. In fact if you are not a boxing fan, you never heard of him. Same with the rest of them on your more recognizable list.

Holyfield is known to everyone. You say the name to a non boxing fan and they will know he is a boxer. His being on Dancing with the Stars only cemented his name more in the public eye.

I would also not call him overrated. Sure he has seen better days, but their was a time when he could have beat anyone on a given day.
