USC quarterback Sam Darnold announced Wednesday he's forgoing his final two years of eligibility with the Trojans to enter the 2018 NFL draft. His announcement came minutes after UCLA quarterback Josh Rosen declared, as Greg Beacham the Associated Press noted: Darnold rose to prominence with a terrific redshirt freshman campaign in 2016. He completed 67.2 percent of his throws for 3,086 yards with 31 touchdowns and nine interceptions. He added 250 yards and two scores on the ground. The 20-year-old California native followed that up by posting 4,143 passing yards, 26 TD tosses and 13 picks across 14 games in 2017. He also had 11 fumbles, however, which raised questions about his ability to protect the ball despite his obvious upside as a passer.
