I was just looking at his record and what impresses me the most is that he never fought a bum. Never even fought a guy with a losing record. Everyone of them was a good to great fighter. Most fighters that moved up in the pros that fast eventually get schooled by a veteran even with the amateur experience a lot of fighters have trouble adjusting. But Oscar was able to move right along and beat ranked fighters when his career was just starting. He may have 4 losses but i don't think there is any other fighter in history who could've taken Oscars path and had the same success without getting derailed early on.
