"[With] radio, we have to be on every single second," said Esparza on the most recent episode of the Blackhawks Insider podcast. "I'm nonstop, so I have to make sure that yes, I have certain ways of saying where [the players] are and how they [play]."
The Blackhawks first launched their Spanish-language radio broadcast in 2016 when the team began their partnership with Univision. For the past three years, TUDN Deportes Chicago 1200 has provided play-by-play announcing.
Growing up in Humboldt Park, Esparza's first love was singing. While he still performs as an Elvis tribute artist today, his other avocation - sports - became his occupation when he got hired by the Spanish radio station to cover the Blackhawks broadcast.
"I watched a video on YouTube, created a demo, [and] sent it over," said Esparza. "And I was on the [Blackhawks] broadcast the next game. So [learning play-by-play for hockey] was self-taught. I said, 'You know what, I want this and I'm going to make it happen.'"
NHL pedigree often finds itself into a hockey broadcast booth, with regional broadcasts often featuring a former veteran of the league who long ago traded in their hockey stick for a microphone. For Moreno, his journey as a color analyst first began with a joystick.
"My passion and love for hockey initially started with NHL '94," said Moreno referring to the legendary video game from the early 90's. "That was what started everything off."
Also having grown up in Chicago, Moreno continued playing NHL video games through his youth. His hockey fandom reached a new level when he went to his first Blackhawks game - the team's 2006 home opener - and then later experiencing the team's Stanley Cup runs.
"I just fell in love with the game," said Moreno. "With the rink, with the excitement. Just the sounds of hockey, because they're very distinct sounds [from] any other sport."
