Castillo could be a great fighter in any era. I don't have any doubt about that, he's a great fighter. But I don't think he was as good as Duran. Duran was just a little bit better overall. Its easy to forget how good he was, at his best like Castillo at 135 and he gave Hagler a tough fight at 160, and beat Barkley at 160. That's freaking ridiculous, as much as I like Castillo, and he's in my top five-ten favorite fighters, I don't see him being able to do anything quite like that.
