Notice in photos 1-3 how Rashad goes on the offensive with a wild left hook while his head moves to the other side, then closes the distance with a right hook to the body, cutting the angle as his head is changing levels moving to his left. This way he closes the distance, gains momentum and goes for an awesome double leg takedown.
Here you have a clear example of a true MMA-specific technique. This is neither boxing nor wrestling, this is MMA. The combo has to be applied in a decisive manner, using the Tyson-style offensive mindset of initiating a sequence of techniques designed to cause specific reactions. There is no time to hesitate. This is a quick 1-2-3 technique with a single breath. Should the takedown fail, your opponent will probably be open to strikes.
