Silva is sick!!! His knees have literally devastated people. They are like razors. When I first started watching I wanted to see straight fights but as I watched more I learned about the ballet that goes on on the ground, espc. how guards work. After I learned about the different mounts and guards I was hooked for life, because anybody can stand up and throw a punch but the real game is on the ground, and I like how just because some one is on their back doesnt mean its over, If a guy on the ground has his gaurd in then all he has to worry about are weak arm shots because the other guy cant get any room to throw a massive punch, its like a well orchestrated machine.Watching Gracie taught me about fightint from your back. Fighting is like Heavy metal , its for everyone UNLESS YOUR TO STUPID TO UNDERSTAND IT!!!
