you should go attend a local event or three. then realize that these guys are top 10% in their gyms. and then realize that only the top 10% of them go from amateur to pro. and then realize that less than 1% of those that go pro end up in the UFC, ever.
then consider the guy who is in the top 10% of his gym, in his 3rd amateur bout, he went 1-2, and looked fucking awful to you (because you're used to watching UFC). and then rethink this post. and then you'll see that you really don't have any idea what you're talking about.
but mostly you should go to the local event because the beer is cheap, it's fun, and it supports MMA.
cheers.
