Hernandez scored 27 points (14 goals, 13 assists) in 115 games from 2015-17 and eight points (two goals, six assists) for the USNTDP's USHL Under-17 team. He scored two goals in four games at the 2015 Under-17 Four Nations Tournament in Puchov, Slovakia.
"Coming in as a 16-, 17-year-old, it was the speed, the hockey sense, everybody had great shots, the goalies were a lot harder to play against," he said. "The USHL, everybody's committed [to colleges], they're all top dogs."
Hernandez moved on in the USHL to play 45 games with Sioux City in 2017-18 and 16 with Lincoln in 2018-19. He scored 12 points (three goals, nine assists) in 61 games between the two teams.
Brooks of the AJHL acquired Hernandez in November 2018, and coach Ryan Papaioannou set out to return him to the scorer that he was in Florida. Papaioannou was impressed by Hernandez's speed, which he said rivals that of Colorado Avalanche defenseman Cale Makar, who played 111 games for Brooks from 2015-17. Forward Taylor Makar, Cale's younger brother, played for Brooks last season.
"We knew the skills and attributes that Randy had, so we tried to set him up in all those situations where he would be a first-line player, where he would play on our power play and try to give him all the opportunities to score points and use the tools that were natural to him and continue to work with him on the defensive side of the puck," Papaioannou said.
Hernandez responded by scoring 25 points (10 goals, 15 assists) in 29 regular-season games with Brooks. His seven points (three goals, four assists) in eight playoff games helped propel the team to the AJHL championship in 2018-19.
While Papaioannou tweaked Hernandez's game on the ice, the 21-year-old made adjustments off it during the summer by becoming more serious about offseason training.
"When I was younger, I just kind of slacked [off]," he said. "I didn't really have a personal trainer; I didn't skate as much as I should have. It was a time I was immature, and I needed to change my habits."
He did extra shooting, ran hills and rigorously worked out in Miami with his older brother, Robert, a demanding former high school basketball team captain.
"He's my motivator, pushing me a lot," Hernandez said. "He wanted it just as bad as I did. He's my big bro, he's tough on me but he loves me. He just wanted the best for me. He'd be there by my side. We'd look at drills together we could do and things that will take me to the next level."
Hernandez said the work helped him become a top scorer in the AJHL. Robert Morris coach Derek Schooley said Hernandez's game is taking shape at the perfect time.
"Everybody matures at a different pace," Schooley said. "He's maturing at the right time heading into college. It took him a few years in juniors to get there. His speed is outstanding, his goal-scoring prowess at the junior level has been outstanding and I think those are things that really will help Robert Morris University in the future."
