In Week 15, Jacksonville hosts Washington at TIAA Bank Field at 1 p.m. EST. Here are five stats surrounding Sunday's matchup:
1. Ronnie the Rookie: S Ronnie Harrison made his first career start at SS in Week 13 against Indianapolis and has taken full advantage of the opportunity. Harrison sacked QB Andrew Luck on a crucial fourth down in the fourth quarter to help the Jaguars secure a 6-0 shutout victory against the Colts. In his second start at SS in Week 14, Harrison registered his first career INT, which he returned 14 yards. Harrison joined Jonathan Cyprien (2013), Reggie Nelson (2007) and Marlon McCree (2001) as the only rookie safeties in franchise history to produce a sack and an INT in the same season.
2. Rating Wreckers: The Jaguars have allowed an average QB rating of 83.4 in 2018, the second-lowest in the NFL. In its last two games at home, Jacksonville faced two Pro Bowl QBs, holding Steelers QB Ben Roethlisberger to his second-lowest QB rating (60.5) in 2018 and holding Colts QB Andrew Luck to his lowest QB rating of the season (66.8). On Sunday, the Jaguars face Washington QB Josh Johnson, who is expected to make his first start since Dec. 4, 2011. Johnson has a 61.6 career QB rating.
3. Safety First: Rookie LB Leon Jacobs tackled Titans WR Cameron Batson in the end zone on punt coverage in Week 14, marking the Jaguars' second safety of 2018, and marked the first time since 2013 the team has recorded multiple safeties in a single season. DT Marcell Dareus and DL Calais Campbell registered the team's first safety when they stopped Jets RB Isaiah Crowell in the end zone in Week 4. Jacksonville's run defense faces a difficult challenge this week as they defend Washington RB Adrian Peterson, who ranks ninth in NFL history and second among active players with 13,148 rushing yards.
4. Home Finale: Sunday marks the final Jaguars home game of the 2018 season. A victory on Sunday would give the Jaguars a winning record at TIAA Bank Field for the second consecutive season. The Jaguars defense has been stellar at home, allowing 15.0 points in their six games at The Bank, which is the fewest points allowed at home by any team this season. Since Doug Marrone took over as head coach in Week 16 of the 2016 season, the Jaguars are undefeated (5-0) in home games in December and look to remain that way this Sunday.
5. Lockdown on Fourth Down: The Jaguars defense has made teams pay for going for it on fourth down this season as they boast the league's top fourth down defense (18.2 pct. opponent conversion rate). Jacksonville hasn't allowed a fourth down conversion since Week 6, and has stopped six fourth down conversions in the last four games, including two stops on fourth-and-goal. Jacksonville successfully limited Indianapolis on three fourth downs in Week 13 and are the only team this season to not allow a fourth down conversion in a game where the opposing team had at least three attempts.
