I agree, the belt is enough distinguishment. It also helps out the eventual title contender in a sense that it's not going to his first five round fight (presuming he's been in a main event before.)

I wonder if this would this apply to all UFC events or just PPVs. I bring this up because Jon Jones has been in the main event on two occasions, but it wasn't on a large PPV card(UFC Live 1/2).

Later.
