Bailey was a three-year starter for the Trojans defense, alternating between outside linebacker and safety. The redshirt junior mostly played safety under defensive coordinator Clancy Pedergast in 2013, leading the team in interceptions (5) while recording 61 tackles and 6.5 tackles for loss. Bailey was named to the All-Pac-12 second team by the league's coaches earlier this month.
According to the school, Bailey -- a policy, planning and development major -- has already earned his degree.
