Tournaments To Determine Champions

What I like about tournaments is that you have several top notch fighters fighting and at the end of the day, the best fighter wins. The following year, another tournament is held and the defending champion has to go through the process again. This would give us a better appreciation of a champion as opposed to the champions who pick and chose there opponents and decide when they are going to fight again. Take the top guys in the weight class, have them draw straws and fight it out to determine the champ.
