After Monday’s spring football practice, Oregon head coach Mark Helfrich spoke to the media and discussed two offensive positions: center and running back. Hroniss Grasu has earned first-team all-Pac-12 honors the last two seasons, so barring anything unforeseen, he will be the starting center next season. But the Ducks still needs backups and Helfrich discussed some of the players who could receive those roles. Helfrich also talked about the running back competition between Byron Marshall and Thomas Tyner.
