I dont see any real reason why Haye cant just do a more active version of what Evander Holyfield did. It was such a safe gameplan and he didnt take any punishment at all.

2 of the cards from the judges in that fight were 114-114 and 115-114 Valuev and Evander hardly engaged. Just take the same blueprint and bustle in once/twice more per round (so still a very safe gameplan) and that would be enough to take it on the cards.

I think if Haye goes in looking for a KO that will be his downfall as he will be tired come the later rounds and lose on points or maybe even get stopped in the second half.
