My guess is Tua KO5. Man is every bit as an animal as Dempsey is and hits harder with that huge left hook. What's your opinions ?
An absolute war. Jack would meet him punch for punch, and he was faster, taller with 3 inch reach advantage and much stronger mentally. There is no evidence that Tua was stronger or hit harder, he was just fatter and he may have had a better chin. I think Dempsey wins this by UD , he just has more advantages.
Tua's too big and refined. Dempsey was a much more talented fighter with more killer instinct and higher IQ. But Tua's size and training make this a quick night. jack won't go down easy, but eventually he just doesn't get back up.
Tua would starch him. This would be a fire fight for as long as it lasts and Tua is too big, strong and powerful for Mr Dempsey.
