Tua was pretty quick,i have to disagree on the feet ,tua rarely used different stances or moved around,he came straight forward ,Ortiz shuffles at different angles,it would be not a easy fight for tua,take into account Ortiz long reach and controlling with a jab.
I do not consider him to be among the better contenders of history. He is perhaps an interesting "what if", but his resume does not make him any sort of standout as a contender.
