I understand that, and it is a likely possibility, at the end of the day it's open to interpretation. I guess I never considered it that way until you mentioned it. Like the early UFC's they are trying to increase the numbers of fans through commercial success of other styles, including Aoki & Schaub is likely to be the start of a growing trend for the brand of MMA fighters appearing at their events. Although, murmurs are that any future MMA fighters being invited will be pitted against other MMA fighters for some level of equality.
In Hindsight it might've been more of a contest if they chose a higher level heavyweight, say a 2nd or 3rd degree blackbelt like one of the Nogueira bros or Werdum, Frank Mir, etc.
