The UFC is modelling itself like a mainstream sports league, with uniforms, exclusive sponsors and such...If they want to be a mainstream league, then they have to act like one...
That means this philosophy of the "money fight" needs to get thrown in the garbage...The money game in the NFL is probably the Patriots versus Cowboys, and something the NFL would love to have, but they don't OBVIOUSLY rig the league to lead it in that direction...
Thus, a fighter like Pena who has been on a winning streak should be fighting for the championship before a fighter who was knocked out and decided to go on a year long vacation...
Therefore, using the "money fight" argument against Pena is not "Etherous," because it goes against the UFC's philosophy of "the best fighting the best"...
