I have only seen a couple of Berto's fights but what I have seen he shows some very nice potential. Right now he is so much better than the people he is fighting that he hasnt had to use any boxing skills to get past them. I do wonder about his defense in one bout he was getting hit flush (the guy had no power thou) so that worries me a little. But Berto has two things you cant teach power and speed, that will at least get him up there to where he will have to have some skills to go on.
