Earlier this offseason, Darnold returned to Southern California to again work under the tutelage of Jordan Palmer. Prior to being drafted by the Jets, many skeptics wondered if the fumble problems Darnold had at USC would persist on the professional level. But he had only one strip sack in Year 1 and that came in the season finale against the Pats.

"I worked on things that I really needed to work on. I think I did that my rookie offseason as well in terms of turning the ball over, but this last go-around — I was able to focus in," Darnold said. "I was also able to watch a lot of my tape from this last year and really figure out how I want to get better."

Darnold will start training camp light years ahead of where he was last July. Not named the team's starter until September 3, he started 13 games for the Green & White while completing 57.7 percent of his passes with 17 touchdowns and 15 interceptions.
