We aren't talking about Royce Gracie who was racking up subs in the 1990's, geez. We are talking about GSP who is still only 34 years old, Bones who is currently still fighting, Anderson is still fighting, you get it? The 4 greats didn't become great in Royce's era. GSP may still fight more, Bones is only 28, you get it? The all time greats are still making their names right now in THIS era.
You conveniently left out Fedor. Cool.
I agree with you and I keep saying "considered" not should. Meaning there "may" be an argument for being a top fighter.
