Since GGG got 750K for this last fight, I believe his next fight, his team have to be in the 1 mill dollar chase. So that fighter have to be somewhat of a draw or have a title. Besides, I can't see GGG moving up because he would a Mayweather fight. So . . .
If not Cotto, Soliman or Quillen. After that it's definitely $1 million at least against Froch or Jcc Jr or Cotto then Ward.
