No they don't
No it doesn't
What they hell is this obsession with belts? This is why UFC thinks it needs to have a title on the line every event and make shitty interim titles if they can't pull it off for real
Guys, I hate to break it to you, but the belt is just an object - a shiny object - but an inanimate object that adds no extra value to the fight or changes it in any way. It started back in the carnival days when they'd have wrestling events. The "belt" was just a gimmick the ringmaster came up with to help sell tickets. A gimmick, that's all it is. Wake up, smell the coffee, and move on
