There's more this though. It's not just a matter of hand speed. Vitor has good skills that enable him to stand in the pocket and counter. He will beat Jones if this becomes a stand up match. Jones would really be a fool to stand with him and I don't think he will. Vitor is going to get taken down brutally, and beat up much like Roa was. Many have done it before. It shouldn't be difficult. He's a natural middleweight, and won't be able to do much about it.
But does he have a punchers chance? No question.
