I'd pick Spinks as he was clearly the better technician than Haye and he also had the power to seriously trouble true HW's like Cooney and Tangstad. Spinks by late KO or by pts if Haye fights cautiously.
Haye blitzes him like Tyson did only without d need of cheating. Yes, I know, only Tyson could KO Spinks and Holmes d way he did, until 1 learns about Holmes' amateur past.. :yep and watches d gr8 use of elbows.. which Haye would not have needed. Maybe it takes Haye a rd or a few more than it took punk elbow, maybe it does not, but Spinks is almost hopeless in dis 1. & Y pol no pablik?
