When you enter the world of great grapplers, EVERYBODY has great technique and strength and conditioning is usually what does make the difference. Since I made my last post on this thread, I've fought in the Super Heavyweight division of two World Jiu-Jitsu championships (No-Gi, two different years). One I came in much physically stronger than the next due to my strength training being effected by injuries. In 2011, I was a better technician and had better cardio than in 2010, but was not nearly as physically strong. I was amazed at how MUCH of a difference it made in my performance. I took home medals from both years and won my pre-lim matches, but the level of competition was actually much tougher in 2010, but I wasn't at the same level, strength-wise and it was a huge difference. My takedowns were stuffed, I lacked the control over my opponents, ect. I even got my elbow snapped trying to escape a keylock (shoulder lock).
