Could it be possible for an all-sports format working in the island on the FM dial? They can carry Miami Dolphins, Heat, Marlins and Panthers games in Spanish to fill air time.
Doubt there'd be much hockey interest there. There sure isn't much in Miami itself! Baseball and basketball would seem like naturals, and maybe even football although I have no idea how much interest there is in American football there as opposed to the rest of the world's football. But is there enough loyalty to those mainland teams in Florida to say for certain that an all-Miami sports format would be the best way to go. The Miami pro teams are so nondescript-to-awful right now that there might be more interest in the glamorous franchises (Yankees, Dodgers, Cavaliers, Warriors, Patriots, etc.) than in those teams.
American football is followed, mostly, by people who went to college on the mainland. There is practically no local High School and no college play. It's a niche sport. And the uniforms are way to hot to be played in in PR.
And yet South Florida is a hotbed of American football, especially at the youth/high school/college levels. The uniforms don't seem to be a problem. Some players wear a jersey a size or two too small, for a bare-midriff look, but others wear all the gear that is worn in football leagues around the country.
By the way, how is NFL football televised in Puerto Rico? Do ESPN and Fox's Spanish-language networks carry the games their English networks do on the mainland? How about the CBS and NBC games? Is there an English TV outlet in San Juan carrying the NFL in English, and if so, which games does it have the rights to?
