Your other two lines from that post aren't really related to what I was saying, but this one is. You're right, people pay for fights they want to see. Unfortunately, like I said, if the attitude of the average "Fan" is "I'm just paying to watch Nate fight Conor again, or "I want to see GSP take a title fight after being retired for several years, and you had better not put anyone on the the card who isn't male and also over 155lbs because "manlets", then the sport will fail no matter what.
As an example, this is the same attitude that allowed Conor to log-jam two divisions and not defend a single title before leaving the sport entirely. Short term, that made money for the UFC. It's also a pretty good strategy for long-term failure. Conor didn't bring new people to MMA. He brought new fans to Conor (as evidenced by the difference in PPV buys when he's not on a card). That's great for Conor but when leadership has decided to throw everything behind him, and he decides he's either done, or at least done w/MMA, what are they going to do?
Same deal w/GSP. I would actually like to see Bisping defend against someone in the currently active top 5. But yeah, let's go ahead and screw those guys and let GSP walk right out of retirement and into a title fight. This is the kind of stuff I mean when I say leadership doesn't take the sport seriously. It just makes me feel like nothing really matters as far as the real rankings go because you can just get on the mic and be a d-bag and talk yourself into title contention, or play on past legacy, etc etc and suddenly the rankings are meaningless. As a fan, if it means that little to the people who are actually running the sport, I'm not sure why I should care either. If people want to see that kind of thing, then go for it. You're not "wrong" for liking or disliking something. Just realize that the reason numbers are dipping has a lot less to do with "women and small fighters" and a lot more to do with the attitude that seems to be expressed in you OP. You can't create a sustainable sport off of super-fights and freak shows, and that's exactly what the UFC has tried to do since around 2014/15.
