There's an article on the main page that suggests Wilder should replace Haye to fight Fury. I think it would be a good step up for Wilder. I don't think it should happen so soon, but it could happen in late 2013-early 2014. And THEN the winner fights Haye. If Wilder wins, Haye-Wilder would be a fun little scrap between two hard hitters with questionable chins.
I think Haye would want the money for the fight. It's only six weeks. If he broke a leg or something, that's one thing, but he deserves the paycheck. Cuts happen all the time.
Doubt Fury's team would risk a loss to Wilder and and see a 5 million pay day disappear and Wilder's not ready for such a big step up.
