"Logic Behind the Leather" David Tua vs Alexander Ustinov

So it seems that the comeback bout between David Tua and Alexander Ustinov at the Claudelands Arena in Hamilton, New Zealand, will take place on August 31st.  There are reports that the match up would have to be postponed due to an injury from Tua, but the fight will go on.  And what a match it will be between Ustinov, who's in contention for a Heavyweight title bout, and Tua, who's making a comeback after two year layoff.  This highly anticipated fight will reveal Ustinov's legitimacy as a heavyweight and Tua's legitimacy as a heavyweight contender after a short retirement.
Alexander Ustinov is a powerful heavyweight, but his heart and legitimacy is questionable.  In his last bout, and first loss in his career against Kubrat Pulev, he took a knee in the 11th round and was counted out.  He seemed to lack the heart and perseverance that it takes to become one of boxing's elite.
David Tua is on the road to reclaiming his status as a dominating heavyweight.  After years of legal and financial troubles, and two years out of the ring, Tua hopes that this comeback will once again make him a formidable contender in the heavyweight division.  Tua, 41, also has a tremendous task of preparing himself physically and mentally for the bout.  Physically he has to be in tip top fighting shape and at the age of 41, many question his ability to perform against Ustinov.
I think that the real questions here are not Tua's punching power or how tough he is, because he's never been knocked out in the 58 matches he's had, but how accurate his distance and timing is.  Ustinov shows his ability to brawl in the ring, something that Tua will probably reciprocate, but leaves himself wide open to Tua's infamous left hook.  On the other hand, can Tua get around Ustinov's reach and penetrate him with his punches?
Ultimately, David Tua has chosen a good comeback match up against Alexander Ustinov, as he has a good chance of defeating him and putting himself in line to contend with other heavyweights.  Ustinov needs to prove that he belongs in the ring with other heavyweights by beating Tua and proving his legitimacy as a boxer.
