People say that Light Heavyweight is a wasteland, meaning there are only two/three fighters that are actually decent; the same is said of Heavyweight... and the SAME is said of Flyweight, Featherweight, and even Middleweight (where people say the division is so shallow that a 42 year-old Yoel Romero that is technically on a losing streak is fighting for the title - which, by the way, I am glad because I don't think he should have lost his last fights, but that's besides the point).
That leaves us with only three divisions that are acceptable: Bantamweight (not even agreed upon by everyone), Lightweight, and Welterweight.
Do you see what I am trying to say? That if you truly analyze the roster and the top 10 of each division, it shows you that the UFC is somewhat of a shitty fighting league. Think about it - the top fighters fight one another multiple times, which is another reason why people typically consider divisions wastelands - because the champs fight the same individuals numerous times because there's "no one else" worthy and the difference in skill between the handful of top fighters and everyone else is too vast (top 3 of Light Heavyweight; top 3 of Heavyweight; top 2 of Flyweight; top 3 of Bantamweight; top 3 of Featherweight.
I am not whining about the quality of the fighters - quite the opposite. I am merely stating that according to the fans, the UFC is a shitty fighting league (they don't realize they are saying this, but they truly are), and thinking about it deeply, yes, the UFC is actually a shitty fighting league. There's no influx of athletes arriving to even the odds. It's always the top 3 fighters, who aren't even typically considered that good by MMA fans, who overshadow everyone else, and those other people are considered uninteresting trash. If UFC is the top dog, that shows you how poorly MMA is doing athletically.
It's like a telenovela, with the exact same characters participating continually, and everyone else is just a side character.
