What does underrated even mean, exactly? Is it guys who deserve a title shot, but haven't got it yet? Guys who, for whatever reason, don't get enough respect from colleagues, fans or pundits? Guys who are simply not familiar to the casual fan? The hardcore fan?
Probably a little of all the above. In general, though, for this list, I'm going to define it loosely as fighters whose prospects are, because of a lack of name recognition or acceptance or some other reason, much brighter than might appear to be the case when compared with their higher-profile peers.
Is that vague enough? Good. That means it's time to get started.
