In 34 years as a head coach, Brose compiled a record of 540 wins, 363 losses, and 79 ties.
[3] He was an undergraduate student while coaching at Concordia, receiving a bachelor's degree in 1962, and also playing on the ice hockey, baseball and football clubs.
When the first NCAA Division II Men's Ice Hockey Championship was held in 1978, the recently rechristened Mankato State University was a part of it, finishing in third place.
Brose coached the Mavericks to the Division II tournament three more times and led the team into the NCHA conference.
Due to Northern Michigan leaving the WCHA after the 1996–97 season, Mankato State was invited to participate in the conference tournament despite not being a full member.
[7] In his final season with the program, Brose led the newly renamed Minnesota State to a fourth-place finish in the conference and helped them advance out of the first round for the first time, receiving the WCHA Coach of the Year honors, as much for the season as his body of work leading up to his final year.
