The heavyweight title fight between Cain Velasquez and Junior dos Santos ended so quickly that it disapponted some people. I, like many, think the UFC and Fox should have shown Guida-Henderson instead of 30 minutes of of hype. But, I don't understand why people think it's a total failure. If you look at the details of the fight, I think any MMA fan can still enjoy it, even if it was short.
Immediately, Dos Santos was superior in terms of speed to Velasquez, so, he didn't need to attack first. Dos Santos was able to react to Velasquez's attack and counter, instead. Moreover, dos Santos is great at using his back step to create an angle for his dominant right hand. He goes to the right side to set up that right hook, making it much harder to see.
Dos Santos throws a left hook with 4:22 remaining, and Velasquez answers with a left hook of his own. I think that movement made dos Santos try it again. At 4:18 remaining, dos Santos shows a left hook feint, then throws a right hook to the body, bringing the attention to Velasquez's torso.
Then, with 4:05 remaining, dos Santos throws a left jab, which I don't think he had any intention of landing. If you watch the replay at the end of the fight, it looks like he uses the jab to gauge Velasquez's movement. He expected Cain to answer with the left hook, and he was able to counter with his right hand. Look at the post-fight replay and watch the mechanics.
Short fights can still have plenty of rich MMA content if you really look.
