*Neither were the hardest punchers at heavy... but both had balls. How would a fight between these two have gone?
Spinks had plenty of power at heavy. Significantly more than Byrd. Spinks too awkward and fast for Byrd's speed advantages over his bigger, slower opponents he had at heavy. Spinks W15 If not a late stoppage. Byrd simply doesn't have the power to keep Spinks honest.
*Byrd was pretty elusive... i doubt Spinx could Ko Byrd when only the very best Ko'ed Byrd in his prime... he'll ,he even got in there with Tua, whom he beat... Byrd does get the "i'll get in with anyone"award... and with no power to boot. I agree though, i think Spinx wins via UD.
