Take a look at Sherdog's most recent (12/22/14) top 10 heavyweight ranking. With the exception of Travis Browne and Stipe Miocic, all other top fighters have been around for almost a decade. I don't even know of a up-and-coming "breakthrough" fighter or a dominant veteran to follow in that division to keep me interested (e.g. an exciting up-and-commer like Conor McGregor or Kyoji Horiguchi, or a dominant fighter like Jon Jones). Why is this so?? Are potentially great heavyweights entering other sports (NFL, NBA) for the money? Should the UFC scout deeper into the international market to find another Fedor? What I think heavyweight division needs is an mma-version of Mike Tyson (a sort of tragic-hero that is vicious and exciting) or another Fedor (an exiting, enigmatic, all-around likeable fighter) What are some solutions to progress the heavyweight division?
