One of the most attractive aspects of weight class-based sports like boxing is that they provide a venue for the smallest of competitors. A 112-pound athlete has few options in team sports, but in boxing he can aspire to become a world champion.
Media coverage can still be hard to come by, though. While the smallest weight classes have a healthy following across Asia, the Pacific and throughout Mexico and Latin America, it is rare to see even the best flyweights featured on prominent, televised cards in the United States.
That can make it difficult to get a really accurate picture of who is truly the best among the smallest pool of fighters, and how they stack up against each other. To put together this ranking, I have relied on The Ring ratings, Boxrec.com ratings and records, and a lot of time searching for fights on YouTube.
