Logan Cooley became the highest player born in Pittsburgh taken in the NHL Draft when the Arizona Coyotes selected him No. 3 in 2022. He emerged as a legitimate forward in the NHL after the Coyotes relocated to Salt Lake City and signed an eight-year, $80 million contract ($10 million average annual value) with the Utah Mammoth on Oct. 29, 2025. At the time of the signing, Cooley was second in goals (33), third in points (77), fourth in assists (44), tied for third in power-play goals (10), and fifth in power-play points (24) dating to Utah's inaugural season in 2024-25.

Cooley started the 2025-26 season with 12 points (eight goals, four assists) in 11 games, and had the first natural hat trick in Mammoth history as part of a first four-point game in the NHL (three goals, one assist) in a 7-4 win at the St. Louis Blues on Oct. 23. He became the first player since the franchise relocated to score four goals in a game when Utah defeated the Vegas Golden Knights 5-1 on Nov. 24. He also had an assist to become the second Mammoth player with a five-point game, joining Clayton Keller (one goal, four assists Feb. 27, 2025).

He scored Utah's first-ever Stanley Cup Playoff goal during a 4-2 loss to the Vegas Golden Knights in Game 1 of the Western Conference First Round. He then scored the go-ahead goal late in the third period of a 3-2 victory in Game 2 for the franchise's first postseason win. At 21 years, 352 days, Cooley became the youngest United States-born player in NHL history to score in each of their first two playoff games, a record previously held by Mammoth captain Clayton Keller (22 years, six days).

Cooley started playing hockey at 5 years old in the first season of Sidney Crosby's Little Penguins Learn to Play Program in 2008-09. He continued playing for Pittsburgh-area teams until joining USA Hockey's National Team Development Program in Plymouth, Michigan, in 2020. In 2021-22, Cooley was second on the NTDP Under-18 team with 75 points (27 goals, 48 assists) in 51 games, his average of 1.47 points per game was first, and he had 20 points (eight goals, 12 assists) in 15 games against NCAA competition.

He helped the United States finish second at the 2022 IIHF Under-18 World Championship with 10 points (three goals, seven assists) in six games and was voted the tournament's top forward. His 12 points (four goals, eight assists) tied for the team lead at the 2025 IIHF World Championship, when the United States won its first gold medal in 92 years.

Cooley played one season at the University of Minnesota in 2022-23, when he helped the Gophers to their first NCAA national championship game in nine years, a 3-2 overtime loss to Quinnipiac. He was also named a finalist for the Hobey Baker Award given to the top player in Division I men's hockey, won by Michigan forward Adam Fantilli.
