And since being drafted, the 20-year-old has been living out a childhood dream.
"It still doesn't feel real to me," Mazur said. "It's something that I really can't put into words."
Growing up, Mazur, who is an alumnus of the Little Caesars AAA Hockey Club, loved practicing at Joe Louis Arena and then at the BELFOR Training Center inside Little Caesars Arena.
"Having that history, meeting players every day and having coach Kris (Draper) be my mentor in a way while he's bringing in people like (Niklas) Kronwall to skate with us was something you really don't have an opportunity to do when you're younger," Mazur said about his experience with Little Caesars. "But we did here and that was pretty special."
After playing seven games for USA Hockey National Team Development Program's (NTDP) under-17 team in 2018-19, Mazur was selected third overall in the 2018 USHL Phase I Draft by the Tri-City Storm. He tallied 13 points (6-7-13) in 47 games the following season with Tri-City, then was named captain for the 2020-21 season, notching 20 goals and 24 assists in 47 games.
This past season, Mazur concluded his freshman campaign at the University of Denver with 14 goals and 24 assists in 41 games, helping the Pioneers win the 2022 NCAA Championship in April and garnering NCHC Rookie of the Year honors.
