Event: UFC 82 3/1/2008
Winner: Silva
Winning Move: Rear Naked Choke (12:30 mark)

This was the fight that made people start saying the Spider is the pound-for-pound king. In his previous six UFC fights, he won five with strikes and one by submission. He was the reigning middleweight champ.

So here comes Henderson, a wrestler with punching power, whose game plan was to take Silva down and rough him up. That worked in round one but in round two Silva touched up Henderson with strikes and took him to the ground.

Remember that movie Momento? That sums up Henderson's night. He forgot Silva was a black belt in BJJ under Nogueira. Silva manuevered Henderson into a bad position, took his back and choked him out. Since then, people have been calling Silva the greatest of all time.
