I would agree and disagree. In my opinion, MMA is exactly what its called, Mixed Martial Arts. A combination of skill sets, designed to be the most efficient in the octagon. Looking at the current line up of champions, a wrestler with good boxing seems to be the most efficient means of winning. i.e gsp, bones jones, cain valesquez, Benson henderson, etc. Generally yes, most fighters start with one strong skill set and add others along the way. However, most gyms these days advertise MMA classes, a lot of newer, younger fighters are being brought up learning pure MMA as its own discipline.
What I was referring to, in my previous post, was how I enjoyed watching two different styles, clash. When the UFC tournaments started it was one discipline against another, so it answered the age old question, which fighting style is the best. We learned real quickly that Jiu-jitsu was the king of disciplines in a one vs one scenario. However, we also learned as the sport progressed into what it is today, that MMA is generally better than pure Jiu-Jitsu (see the Gracie vs Hughes fight.)
The UFC we watch to today is certainly a better offering to the main stream viewer. And yes, no one likes watching a wrestler lay' n' pray. All I meant was that as someone who is fascinated by all the different combat styles, the older tournament style was more intriguing to me. Either way, its all fun to watch.
