Marcus McMaryion delivered the news to Kevin McGiven Sunday morning. First, McMaryion shared with his quarterbacks coach that he had decided to transfer from Oregon State three weeks before its season opener. Then, McMaryion asked for tips on how he could improve at his next destination. That illustrates the type of player, person and teammate OSU is losing, McGiven said. Still, the Beavers will now press on with their current crop of quarterbacks, which includes three signal-callers who have taken snaps against Football Bowl Subdivision competition. "Ultimately, at the end of the day, (he) made the decision that was best for him," McGiven said. "We're gonna support him and help him any way we can, obviously, in that process. "We'll move forward. We've got to continue to try to get Jake (Luton) ready for Game 1." McMaryion's decision to leave OSU comes less than a week after coach Gary Andersen officially named Luton, a junior college transfer, as the Beavers' 2017 starter. McMaryion split second-team reps with Darell Garretson during OSU's scrimmage in Bend Friday night. "I want to thank the fans of Beaver Nation, the coaching and academic staff, and my teammates for a great three years," McMaryion said in a release. "As I close this chapter of my life as a graduate, the next chapter awaits. It has been a privilege representing this program on and off the field. For my OSU brothers on the field, remain 11 strong and have a great season." McMaryion, a junior who will be immediately eligible for two seasons at an FBS school because he's already earned his undergraduate degree, slid up and down the depth chart throughout his time at OSU.
