Any title is only worth the guy carrying it to us, but for fighters they are a great insurance. Even the most phony trinkets mean you have a stream of income, people want to fight you and you aren't going to get peanuts when you might otherwise. A fight like Haye-Fury is huge because they have some celebrity status, but there are only ever a handful of guys who stand to make that kind of money anyways. Title's on the other hand mean guys we wouldn't have a clue about otherwise, are substantially higher draws than they would be.
