Opening camp: Duke

Schedule: Practice starts at 6:15 p.m.

What’s new: Marion Hobby was promoted to assistant head coach/defensive coordinator and will be calling the plays for Mike MacIntyre, who is now head coach at San Jose State. Duke will still be a very multiple defense.

Sidelined: Freshman defensive back Quan Stevenson is out indefinitely with a leg injury.

Key battle: Running back. Jay Hollingsworth tops the preseason depth chart, but Desmond Scott, Patrick Kurunwune and true freshman Josh Snead will all be pushing for playing time. Hollingsworth started two games last year -- against Maryland and Virginia -- and Scott started four games and led the team in rushing as a true freshman with 262 yards.

New on the scene: Junior college transfer tight end Cooper Helfet. He is listed as a backup tight end, but he could emerge as a downfield threat in the passing game. He played wide receiver primarily at Santa Rosa Junior College and has two years of eligibility remaining.

Breaking out: Receiver Tyree Watkins. He will be a redshirt freshman after earning a medical hardship because he suffered a season-ending knee injury last year. He’s in a crowded, talented group that includes some of the ACC’s top receivers, but Watkins’ teammates have raved about him this offseason.

Don’t forget about: Safety Lee Butler. He played primarily at corner his first two seasons, but moved to safety this past spring. He had a good spring and recorded the team’s top vertical jump (40.5). He played in 11 games last year, started seven, and had 39 tackles, one interception and four pass breakups.

All eyes on: Sean Renfree. For the first time in four years, Duke will have a new quarterback. Renfree has big shoes to fill, as Thaddeus Lewis set or tied 56 school records. Renfree completed 34 of 50 passes for 330 yards, four touchdowns and two interceptions as Lewis’ backup last year. He suffered a season-ending knee injury against Georgia Tech and had surgery to repair his torn right ACL on Nov. 23. He was limited this past spring.

Quotable: "I think we'll run the ball better this year. We're going to throw it. Everyone knows that. But we are going to run it better." -- Duke coach David Cutcliffe
