Ok, your questions about Floyd:

1) Hell no a loss wouldn't mean Floyd wouldn't get into the Hall of Fame. If he lost and retired he'd still make the hall easy.
2)I suspect he'd want to come back if he lost but I don't think he'd necessarily have too.
3)I don't totally understand the third question. Do you mean should PBF get S*** on for fighting dominant champions in each weight class except 140. I don't see why of course I'm not sure if he really has fought "dominant champions" in each class but he's definitely fought some good to great ones.

And Hatton:
1)You could make a case, he's already in the top ten and a win over PBF would mean a win over the recognized best fighter in the world, a guy with almost god status in some people's eyes. Of course you could pick his record apart if you wanted. I thought the win over KT was a good win and don't buy into the S*** about KT being shot, nobody was saying that beforehand. On the other hand Castillo I think was a bit shot.

2)I would assume so. Some people might still list Calzaghe although Hatton would have the better wins.
3)I don't know, some people might still say a guy like Jimmy Wilde but I don't really try to comment much on guys who I've never seen.
4)Yes. I mean besides the obvious "if Barry McGuigan..." comments, he probably would have deserved it. I guess his career could go totally wrong after that though.
