Someone by knockout and sadly, more likely Foster, early. Foster was a monstrous light heavy but when he fought larger men, and Haye is actually a big man, just not in relation to the super heavies, he usually got beaten. Foster was a tall, very scrawny light heavyweight. Haye was a massive hard hitting cruiser and would've been a good full sized heavy in the seventies (I think he's an average sized heavy now, actually). Probably too strong anyway. Foster does still maintain his punchers chance, considering Haye's less than stellar chin.
