Smaller organisations have shittier fighters as well as smaller cages. Shttier fighters are easier to finish. Cage size is not the only factor when comparing TUF and WEC to the UFC for finish rates. Terribly thought out and unscientific article.
Every amateur event I attended has had a tiny cage, negating the ability for footwork and decent wrestling. It's just two guys with no room for skill, forced to grab each other and fall over or swing wildly on the feet. That's not what the UFC should be all about.
