The only problem I have with them taking the main event spot is I don't get Machida vs. Hendo 5 rounds. I am having potentially 5 rounds of greatness reduced to 3 because a no-name is going to get arm barred by an average at best fighter in the first round.
As for them main eventing outside of that, it's a championship fight and champions fight in the main event, that's just how that works and I'm not upset about it beyond what I mentioned.
As for it not selling well, we will see what the final numbers.
