Who would win?
considering that Ruiz almost dropped Valuev and was able to land cleanly on Valuev with his power shots and a stalking style, I think Marciano would have TKOed the giant.
why was Valuev surprised when he heard he won?
wow, he sure did have a surprised look on his face. I didnt notice that when I first saw the fight.
Valuev is so open to...anything basically...I think Marciano could just throw overhand right after overhand right, and all Valuev would do is jab and eventually run out of gas.
Valuev wouldn't be able to hit a crouching Rocky Marciano...

Seriously, Ruiz had such success mauling Valuev when he closed in that I would not be surprised at all if Marciano was able to pull it out somehow.
I don't really have an idea how it would play out because I've never seen such a size/height difference in a boxing match.
