Wild thing, you make my heart sing.
It's one of the many lines used in the Major League movies to describe Rick "Wild Thing" Vaughn. Other than looking like a wild animal at times, the nickname was used to describe Vaughn's pitching abilities early in the film.
Yet, with the help of some correctional lenses, Vaughn went on to become the savior of the fictional Cleveland Indians team. The same could be said of the fighters appearing on this list.
Sometimes they come in looking like "Scumbag Steve" on his first day of kickboxing class, while other times they can execute a game plan to perfection.
And other guys on this list don't have to worry about their performances in the Octagon as much as their performances in front of a microphone.
It's the prospect of not knowing what you're going to get when the lights go on that make these fighters the biggest wild cards still on the UFC roster.
