BJJ is more effective than wrestling in finishing fights. Wrestlers are doing well in UFC because they all incorporate JJ submission techniques. Wrestling teaches how to control an opponent but not how to defeat him. Also, while size and strength is an advantage, many JJ techniques have nothing to do with strength. For example, a 145 lb man could apply an ankle lock to the strongest 260 lb wrestler in the world. Nobody can lift more than 145 lbs with their ankle.
