Sam Cosmi

Early life

Cosmi was born in Humble, Texas, on February 16, 1999. Cosmi played football at Atascocita High School, where he was named to the first-team All-District 21-6A and second team 6A All-State as a senior. Rated a three-star recruit, Cosmi committed to play college football at Houston over offers from TCU and Memphis but flipped his commitment to Texas after Houston coach Tom Herman was hired by the school.

College career

Cosmi redshirted his freshman season at Texas. He played in all 14 of Texas's games as a redshirt freshman and started the last 13 at right tackle and was named an All-Big 12 Honorable mention by the coaches. He helped the team reach the 2018 Big 12 Championship game and upset Georgia in the 2019 Sugar Bowl.

He started all 13 games as a redshirt sophomore and was named second-team All-Big 12 Conference. He was also an Offensive Lineman of the Year honorable mention. That season he helped the Longhorns win the Alamo Bowl and finish ranked in the top 25. In a game against the West Virginia Mountaineers that season, he caught a lateral pitched to him by Sam Ehlinger and ran 12 yards for a touchdown, which set the record for the longest TD run by an offensive lineman in Big 12 history. Cosmi considered entering the 2020 NFL draft, but opted to return to Texas for his redshirt junior season.

Cosmi was a team captain in 2020. He started the first eight games of the COVID-19 shortened 2020 season before opting out of the remainder of Texas' games in order to prepare for the 2021 NFL draft. He was a unanimous first-team All-Big 12 selection, second team Academic All-Big 12, an Honorable Mention for the Offensive Lineman of the Year award, and a 3rd Team AP All-American.

Cosmi's parents immigrated from Romania to the United States in the early 1980s. He is a Christian. Cosmi married his wife Blair, whom he met at the University of Texas at Austin, in March 2023. They have two children together, a daughter who was born in 2024 and a son in 2025.
