One guy would be effective at landing his ineffective punches. The other would be ineffective at landing his effective punches. It adds up to a Klitschko decision.
Tua would quit. His nose would cease to be effective after around 8 rounds, and his heart would soon follow.
Tua will lose...but he won't quit...and he would not take as much damage as the recent opponents of Vitaly...
Tua gets jabbed until his fat little head hurts. See Tua v Lewis for a demonstration of how this goes down. MTF
This might not go down well......but I see Vitali hitting him twice as often. Lewis chastened Tua and kept him honest....Vitali wouldn't take any of his shit and would only take a backward step with a view to smashing him in the face 3 or 4 more times. I sincerely believe he would take Tua's heart, which is no great stretch...Chris Byrd almost did it, another couple of rounds of that and Tua would have packed in. Stopping Tua isn't a question of power, it is a question of repetition. Tua would simply get sick of it.
Agree with Irish. Vitali makes him retire in his corner like he's made so very many other fighters thoughout his career.
