Duke has become one of the favorites to repeat as Coastal Division champions for several reasons.
Here is one of the biggest: Duke is the only team in the ACC to return its leading passer, rusher and receiver from a year ago. The Blue Devils return their top two leading tacklers, too.
In all, Duke returns 72 percent of its offense. Only Virginia returns more in the ACC, though the Hoos are changing quarterbacks and only produced two wins with virtually the same players a season ago. Plus, their offense took a hit in the offseason when leading receiver Jake McGee decided to transfer.
What should give Duke an edge is the veteran experience and leadership it will have with returning quarterback Anthony Boone, receiver Jamison Crowder and rusher Josh Snead -- all seniors. Crowder is the headliner of the group, after catching an ACC-record 108 passes a year ago for 1,360 yards. He needs just 1,153 yards to set the school and ACC career receiving yards record.
Snead will once again split carries in the backfield -- the way Duke has done in recent history -- though some depth does have to be developed at the position. Boone will share some of the load at quarterback as well, but there will be much more placed on his shoulders with the departure of Brandon Connette.
That is where the Blue Devils lose the largest percentage of their offense -- 25 percent out of the 28 percent that is gone. Losing Connette means losing 14 of the team's 28 rushing touchdowns from a year ago, along with 1,212 passing yards and perhaps the most reliable backup quarterback in America. Thomas Sirk is expected to contribute, but it is too early to say what exactly his role will be once the season begins.
Still, Duke is the only team in the league with its offensive nucleus intact, an offense that -- by the way -- ranked No. 3 in the ACC. Florida State nearly does with Jameis Winston and Rashad Greene back. Though the Seminoles lose leading rusher Devonta Freeman, they believe Karlos Williams will be able to step right in and fill those shoes. Several other teams return two among their top passers, rushers or receivers: Pitt (RB James Conner, WR Tyler Boyd), Syracuse (QB Terrel Hunt, WR Ashton Broyld), Virginia Tech (RB Trey Edmunds, WR Willie Byrn) and Louisville (RB Dominique Brown, WR DeVante Parker).
Of these teams, only Syracuse returns 70 percent or more of its offense. Still not quite as much as Duke.
