Not great, very good. The current era will only allow a fighter to do so much IMO. The old time greats are untouchable in my view. The competition in previous eras was unarguably better. It's just a different time. But the man has beat everybody put in front of him and is the best of his era. That's all he can do.
Not in the same weight class at the same time? Like Mayweather vs Morales, Berrera...? And Duran? C'mon man...
