The UFC has come a long way since it's humble beginnings, and MMA fighters have continued to evolve along with the UFC and other MMA promotions.
The UFC was very raw when it began; bare-knuckles, no rules, no rounds, tournament style.
Similarly, the original fighters were very raw as well. Some of them were kick-boxers, wrestlers, grapplers, and some of these guys looked like they lacked any legitimate fighting background at all.
But as Bob Dylan put it, times are a changing. The UFC just held there 100th PPV event (not technically the 100th event, but who's counting?). The fighter's knuckles now sport five ounce gloves, and there are many rules in place to keep their fighter's safe.
The UFC is also said to be worth more than one billion dollars at this point. Fighter's have evolved drastically as well, as the old school one dimensional fighters are almost completely extinct in the sport. Well rounded is the name of the game, but even being well rounded at this point isn't enough to wear gold.
The fighter's who wear gold around their waist are the elite, the cream of the crop, the alpha male of their particular weight class. For the first time fighter's who are considered to be No. 1 contenders end up looking like B-level competition when they step into the ring with the title holders.
Let's take a look at each weight class; the champion, the challengers, and let's ask ourselves...where are the challengers?
