I am using "intriguing" in the context of arousing the interest or curiosity of something.
For me, the lineage of great boxers from Puerto Rico is a rich, dramatic and, often tragic one, as many of the fighter met with difficulties both outside the ring or after they finished their careers. In this regard, Puerto Rico has produced a most compelling tapestry of sports in general and boxing in particular. In fact, nowhere are you likely to find more world champions per capita in my opinion.
This island nation has a great number of major league baseball players who are now active, thus making baseball one of its most popular sports, but Puerto Rico also has a disproportionate number of boxers who, over the years, have either been World Champions or top contenders.
