Is it by how many wins he has on his records? Is it by how many records he's broken? How many title defenses? His character? How he wins rather than how many wins? Just curious to see what people say since so many disagree on who they think is the greatest of all time in MMA. Thoughts? I would have GSP at the GOAT based on records, Silva as the GOAT in terms of how he wins and JBJ in terms of how many wins he has on his record and how he fights.
