I think he has the ability to use his boxing skills to get him through the early rounds. Just think when his pace slows down, rios pace will catch up with him. His loss to katsidis I think was a confidence issue, he will definatley have confidence again after his good win against Murray. However as I said before rios is the real deal, and would knock Mitchell out. I really don't think Mitchell should be looking for such a strong fighter. There are some top 135 fighters Mitchell can certainly mix with, but Rios isn't one of them.
