Holyfield v. Hagler P4P

People tend to forget that Evander in his prime was nearly invincible when facing opponents of his size (his only struggles were at heavyweight to opponents with 20-40 lbs on him, and Dwight Qawi at cruiser to which he seriously answered the call both at the end of the 1st fight and in destorying Qawi in the rematch in 4). Hagler never had the obstacle of giving so much weight to an opponent like Evander did, and the argument could be made that Holyfield was just as dominant at cruiserweight as Hagler was at middleweight. I don't see any other way of this fight turning out other than a brutal bloody war from start to finish. Which way would it go?
