Alex Vlasic Bio
Alex Vlasic (born June 5, 2001) is an American professional ice hockey player who plays as a defenseman for the Chicago Blackhawks of the National Hockey League (NHL). Selected by the Blackhawks in the second round, 43rd overall, at the 2019 NHL Entry Draft, he has developed into one of the franchise’s promising young blueliners. Standing 198 centimeters tall, Vlasic uses his size, mobility, and defensive awareness to handle difficult matchups against opposing top lines.
Early Life and Background
Alex Vlasic was born on June 5, 2001, in Wilmette, Illinois, to parents Tara and John Vlasic. He grew up alongside his older siblings, Emma and Eric, both of whom were involved in competitive ice hockey. His sister, Emma, played at Yale University and later skated with the Connecticut Whale, while his brother, Eric, participated in the Chicago Blackhawks special hockey program. The household’s deep connection to the sport helped shape Vlasic’s early interest in hockey.
Vlasic is of Croatian descent, with his grandfather having immigrated to Montreal. Despite growing up near Chicago, he became a fan of the San Jose Sharks because of his cousin Marc-Édouard Vlasic, who played for that franchise. Vlasic began skating at the age of three and joined the Wilmette Braves at the Mite, Squirt, and Pee Wee levels. He played forward until the age of nine, when he switched to defense, a position that would eventually define his professional career. At age thirteen, Vlasic was diagnosed with celiac disease, which prompted his family to adjust his diet and daily routine.
Path to Professional Hockey
Vlasic’s competitive path began with the Chicago Young Americans and the Chicago Mission youth programs. While playing for the Chicago Mission Midget U16 team, he committed to play college hockey for the Boston University Terriers. At the time of his commitment, he was also regarded as a top-five prospect for the Ontario Hockey League (OHL), though he ultimately chose the NCAA route.
Before arriving at Boston University, Vlasic spent time with the USA Hockey National Team Development Program (NTDP) during the 2017–18 United States Hockey League (USHL) season. He has credited the NTDP’s intense practices and coaches John Wroblewski, Greg Moore, and associate head coach Dan Hinote with sharpening his skating, strength, and overall game. The experience prepared him for the rigors of collegiate competition in Hockey East.
Alex Vlasic Career
Early Career at Boston University (2019–2022)
Vlasic enrolled in the Boston University College of Arts and Sciences and played three seasons with the Boston University Terriers. Following his selection by the Chicago Blackhawks in the 2019 NHL Entry Draft, he reaffirmed his commitment to the collegiate route. During his freshman year in 2019–20, he appeared in 34 games and recorded four assists, with his first collegiate assist coming on October 18, 2019, in a 4–4 tie against Northern Michigan. When the season was cut short by the COVID-19 pandemic, Vlasic and his sister built a makeshift weight room in their basement and skated at a local rink while working with Tristan Musser of the Chicago Steel and Brian Keane of Prodigy Hockey.
In his sophomore season, Vlasic’s confidence grew as he learned to use his size to protect the puck and win battles. He recorded his first multi-point game on January 23, 2021, in a 5–1 win over the University of Maine, then scored his first collegiate goal on February 5 in a 4–3 overtime loss to Boston College. By March of that season, he had posted three goals and five assists for eight points through 15 games.
Collegiate Breakthrough (2021–22)
During the 2021–22 season, Vlasic emerged as one of the top defensive defensemen in Hockey East. His head coach praised him as an elite skater for his size, a testament to his rare combination of mobility and length. He led the Terriers with 50 blocked shots while also contributing one goal and a career-high seven assists for eight points. His strong two-way play earned him Hockey East All-Star honors at the conclusion of the season.
Chicago Blackhawks Era (2022–Present)

On April 25, 2024, the Blackhawks rewarded his steady development with a six-year contract extension, signaling his importance to the team’s long-term plans.
Driving Style and Strengths
Although the term is more common in motorsports, Vlasic’s “driving” force on the ice lies in his poise, gap control, and reach. He excels at breaking up rushes, winning board battles, and using his 198-centimeter frame to clear the front of his net. Coaches have noted his elite skating for a player of his size, allowing him to escort opponents from the defensive zone and join the rush when appropriate.
