Inevitably the first question Oregon State coach Mike Riley faces these days is about who is going to be his starting quarterback, Sean Mannion or Cody Vaz.

Both players traded off last season when the Beavers went 9-4 and finished third in the Pac-12 North. And both will compete for the starter's job when fall camp opens for Oregon State on Monday.

Riley says the coaching staff has the difficult task of trying to "project" which quarterback will be more consistent.

Mannion threw for 2,446 yards and 15 touchdowns, with 13 interceptions in 10 appearances. Vaz, hampered down the stretch by an injury to his left ankle, threw for 1,480 yards and 11 touchdowns, with three interceptions, appearing in seven games.
