I'm not sure how Hendo would be ahead of Marquardt in the rankings. Nate seems to have been more dominant in his fights. Maybe those two should fight as well.
Further, I really don't understand Leites unless the UFC just doesn't feel Okami deserved the shot. I'm guessing they didn't and honestly, I don't see it either. Okami fought Anderson in another organization and got a DQ win, but nothing then or now tells me he has as good a shot at beating Anderson as the other top contenders. The loss to Franklin is likely what cost him his position.
