in his younger days, with amato or rooney and in his prime, tyson did not, and i repeat did not have any issues.. he didnt lack stamina, he didnt lack focus, he didnt lack heart..

he came well prepared in his prime, and tua wouldnt stand a chance. if we are talking prime tyson vs prime tua.

tyson would be so much faster, have much better timing.. cant see tua winning this unless its a lucky punch..
