If not Vitor then who? Had Rockhold or Bisping won their fights they would number one contenders and facing Anderson Silva. So what does Vitor do...KO them with the spectacular style headkicks that knocked him out.
There's lots of options. Rashad could make a pretty penny if he decides to drop down and challenge Silva, there's also Mousasi and Jacare who are only a win away from a title shot as well.
