Marcus Ardel Taulauniu Mariota (born October 30, 1993) is an American football quarterback for the Tennessee Titans of the National Football League (NFL). He was drafted by the Titans second overall in the 2015 NFL Draft. He played college football at Oregon, where he was the starting quarterback from 2012 to 2014. As a junior in 2014, Mariota became the first Oregon player, as well as the first Hawaii-born athlete, to win the Heisman Trophy.
Mariota was born in Honolulu to Alana Deppe-Mariota and Toa Mariota and has a younger brother, Matt Mariota; he is of Samoan descent on his father's side and German descent on his mother's side. He grew up admiring the quarterback play of fellow Samoan Jeremiah Masoli, who was also a standout quarterback at the Saint Louis School and the University of Oregon. Mariota describes himself as a dedicated Christian.
Mariota attended the Saint Louis School in Honolulu, where he was a two-sport star in football and track. In football, he was relatively unknown until late in his high school career due to not starting until his senior season. As a senior, he helped lead St. Louis to an 11–1 record and the state title while being named PrepStar Magazine All-West Region and Interscholastic League of Honolulu Offensive Player of the Year. Mariota threw for 2,597 yards on 165-of-225 passing attempts (64.7%), including 32 touchdowns against only five interceptions. He also rushed the ball 60 times for 455 yards (7.6 yards per carry) and seven touchdowns. Mariota was named to the NUC All World Game alongside eventual 2012 Heisman Trophy winner Johnny Manziel.
