Navy vs. No. 13 Notre Dame in Dublin, Saturday, 2:30 p.m. ET (NBC; Sky Sports)

Line: Notre Dame by 20 1/2, according to FanDuel Sportsbook.

Series record: 81-13-1

WHAT'S AT STAKE?

Notre Dame can't afford another slow start after opening last season 0-2. The Irish finished 9-4 but it was the first time since 2016 that they failed to win at least 10 games. Marcus Freeman enters his second full year as head coach. Anything other than 4-0 heading into the Sept. 23 showdown with Ohio State would be a major disappointment. Navy's Brian Newberry is making his debut as head coach.

KEY MATCHUP

Navy defense vs. Notre Dame QB Sam Hartman, who transferred after a record-breaking career at Wake Forest. Hartman has a solid supporting cast with AP preseason All American LT Joe Alt anchoring the line. Notre Dame will try to establish the run with Audric Estimé, who averaged 5.9 yards per carry last season. The Irish will need to contain Navy DE Jacob Busic, who has started 24 straight games for the Midshipmen. Busic had six sacks, 8.5 tackles for a loss and two forced fumbles last year.

PLAYERS TO WATCH
