It makes for a boring fight but it's boxing not cage fighting. Valuev missed everything and got rocked majorly in the last round. He barely touched Haye.
They are not Haye's usual tactics but they were the right tactics for the fight. He realised it was too big of a size difference for him to go and rush him with Hayemakers. He trained for the full 12 and boxed his way smartly to a decision win.
