Floyd via KO in the mid rounds. However Haye is still young and could go on the achieve a lot which might make people change their minds about this match up in due time.
Seems too early to judge. It is fair to say that both men can knock the other out. At this moment i'd go with Haye because he seems to have more one-punch KO power whereas Floyd often scored his knockouts later in fights, plus, Patterson's record against guys who are 6'3 210+lbs that can box is very thin.
