High school Eierman was born to Heather Thurston in
Columbia, Missouri, where he attended
Tolton High School. As a
high schooler, Eierman went on to become the second undefeated wrestler in the history of
Missouri to claim four
MSHSAA titles in four years of
varsity. Entering his senior year, he committed to the
Missouri Tigers. After
graduation, Jaydin changed his last name Clayton to Eierman, honoring his life-long coach Mike Eierman.
College University of Missouri In his first season ('15–'16), Eierman was
redshirted and compiled a 22–2 record at 133 pounds competing unattached in open tournaments. As a freshman, he moved up to 141 pounds and went on to compile a 29–7 record, claimed a
Mid-American Conference title and placed fifth at the
NCAAs, becoming an All-American. As a sophomore, Eierman improved his record to 34–3, repeated as the MAC champion and went on to place fourth at the
NCAA championships. In his final year officially competing as a
Tiger, Eierman racked up a 28–4 record, won his last MAC title (named
Outstanding Wrestler) and went on to keep improving his position as an All-American at
Nationals, placing third. For 2019–2020, Eierman took an Olympic redshirt. As a Tiger, Eierman went 89–14 overall.
University of Iowa In November 2019, Eierman transferred to the
University of Iowa. Coming back to
folkstyle, Eierman went 5–0 during regular season, with notable wins over
Anthony Echemendia from
Ohio State, Chad Red from
Nebraska and Dylan Duncan from
Illinois. On February 8, it was announced that the
Iowa Hawkeyes wrestling team had suspended all team related activities during regular season due to
COVID-19 results. At the
B1G Championships, Eierman made it to the finals with another win over Chad Red, and defeated
Penn State's Nick Lee to claim the title, also helping the Hawkeyes claim the team championship. At the
NCAAs, Eierman got notable
falls to make his first final, defeating ninth-seeded Dresden Simon and fourth seeded Tariq Wilson. In a razor close match against finalist
Nick Lee, in overtime, Eierman was defeated by Lee, claiming runner-up honors and helping to Iowa's first team title in 11 years. He received the
2021 Wade Schalles Award for best collegiate pinner. As the
NCAA granted winter athletes one more year of eligibility due to the
COVID-19 pandemic, Eierman came back for the 2021–2022 season, as a sixth-year senior. == Freestyle career ==
