Coach Geoff Collins has said during spring drills that some players will work out on both sides of the ball. During practice Tuesday, standout receiver Keith Kirkwood was playing defensive end. Last year, tight end Romond Deloatch also lined up at defensive end. Even though he was known more for his offense, Deloatch had four sacks in his senior season. . . . Collins said he has hired Vince Sinagra, 64, as the team's chief of staff. Sinagra will assist Collins and work as a liaison to the equipment, training, and other staffs.
