Already in his first season with Notre Dame, Tagovailoa-Amosa played in every game, although never as a starter, while in the 2018 season, Tagovailoa-Amosa only played two games due to a foot injury that kept him out for the rest of the year.[4] This also meant that Tagovailoa-Amosa missed the only opportunity to clash on the field with his brother Adam in the scheduled match that year against the Naval Academy.[5] From the 2019 season Tagovailoa-Amosa was a regular starter and played all the matches. In 2021, he was named team captain.[6]
On January 9, 2022, Tagovailoa-Amosa declared himself eligible for the 2022 NFL draft,[9] forgoing the additional year of college football afforded to athletes who played the COVID-19 shortened 2020 season.[10]
On August 30, 2022, Tagovailoa-Amosa did not return to the active roster and was released by the Raiders[16] before signing with the practice squad the following day.[17] On November 3, 2022, Tagovailoa-Amosa was placed on the injured list, ending his rookie season prematurely.[18]
Coaching career
On July 9, 2024, Tagovailoa-Amosa was hired to join the coaching staff for the LSU Tigers as a defensive graduate assistant.[19]
Personal life
Tagovailoa-Amosa is a first cousin of Miami Dolphins quarterback and former Alabama quarterback Tua Tagovailoa,[20] while his older brother Adam Amosa-Tagovailoa played as an offensive tackle for the Navy Midshipmen.[21] The difference in the surname with his brother Adam is the result of the profound attachment to the Samoan roots of their family: they are both sons of Tulileie and Saipeti Amora, with their mother, daughter of the great chief Seu Tagovailoa, who wanted one of her nephews to carry on the name of the own family and so it was that Myron already had a double surname at birth, unlike his brother Adam who only had his father's (Amosa). When Seu Tagovailoa died in 2014, his mother Saiupeti wanted all her children to have their grandfather's surname and so Adam also changed his to Amosa-Tagovailoa.[5]
