Video: Marcus Mariota scores four touchdowns in just one half of play

Despite only seeing one half of action, Oregon quarterback Marcus Mariota effectively kicked off his Heisman campaign vs. South Dakota Saturday on Pac-12 Networks.

Mariota filled up the stat sheet, tossing three touchdowns while adding another on the ground in Oregon’s 62-13 drubbing of the Coyotes

Mariota was his usual ultra-efficient self before being shelved at halftime with the game already well in hand for the Ducks. His highlight of the night came in the first quarter when he passed Joey Harrington as Oregon's career touchdown leader with the 62-yard touchdown strike to Dwayne Stanford seen above.
