It's a big advantage in grappling, especially for people with long legs or good dexterity with their legs, since it's almost like they have a second set of arms. It's also good for people that like to kick - it lets them kick from closer up, which can tend to surprise people.
"I don't want them to like me, because when I'm in the ring, punches fly to the face. It is not a tenderness time. I am not falling in love. And he knows that when the fight starts I am kicking faces."
- Wanderlei Silva
