I respect them both as great champions but feel Arguello would be too ring savvy for KT. Probably would stop him later on after a tough fight
Tszyu was a great fighter and hit harder than Argeullo but he just wasn't as great, I think Argeullo would win a close decision.
Not so sure about Arguello the 140 pounder V Tszyu. One fighter in his prime and the other...not You'd have to go with Tszyu 6/10 based on the above although Tszyu could be hurt and knocked down and Arguello was a specialist at it
