Here is a picture of Froch (The man who fought Ward @SMW) and Haye (220lb heavyweight) just to get some perspective. http://www.zimbio.com/pictures/JoETAU4u635/David+Haye+Media+Training+Day/NsZtYyoagPB/Carl+Froch
Soon came out with excuses about his health when pushed to fight Manny. He's ducked the biggest challenges of his career since '07. The dude is a *****.
There's absolutely no chance that Floyd will fight Ward. They are in totally different weight classes. Ward is 168lb fighter who will go upwards, not down. And Floyd is a small 147lb fighter who will sometimes go up to 154. It's just a silly thing to suggest, really, and it does make you sound like you know nothing about boxing.
