Jack had 13 tackles (eight solo) and a sack in Thursday's 30-9 loss to the Titans. Jack put forth one of the most productive outings of his young career Thursday, but it meant little as the Jaguars defense was steamrolled for 238 rushing yards by Derrick Henry. The 23-year-old now has 23 total tackles in the last two games and will look to continue that level of production in Week 15 against the injury-plagued Redskins.
Jack had 10 tackles (seven solo) and a fumble recovery in Sunday's 6-0 win over the Colts. It's the third time this season Jack has totaled 10 tackles, and Sunday's performance eclipsed his tackle total from the previous three games combined. The 23-year-old is an inconsistent IDP option as he is averaging less than five tackles in the nine games he didn't reach double-digits.
Jack had five tackles (two solo) and his first sack of the season in Sunday's loss to the Eagles in London. The two solo tackles tied his lowest total of the season, as Jack continues to be difficult to rely on as an IDP option. The 23-year-old ranks second on the team with 52 tackles (35 solo) heading into Jacksonville's bye in Week 9.
Jack recorded seven tackles (six solo) in Sunday's 20-7 loss to the Texans. Jack started the season strong with 18 tackles through the first two games, but he has otherwise been fairly inconsistent. The 23-year-old does rank second on the team with 48 tackles (34 solo) through seven weeks, as the Jags get set to take on the defending champion Eagles in Week 8.
Jack (ankle) is shifting to middle linebacker in the Jaguars' 4-3 base defense, John Oehser of the team's official website reports. Jack played 97.9 percent of the Jaguars' defensive snaps last season, but his role as the strong-side linebacker in the base defense -- alongside Telvin Smith and Paul Posluszny -- wasn't especially conductive to tackle opportunities. With Posluszny retiring, Jack will slide over to a more favorable position in the middle while Blair Brown likely takes over on the strong side in the base defense. Given that he's also locked in next to Smith in nickel packages, Jack shouldn't have much trouble improving on last year's mark of 5.6 tackles per game. Smith and Jack may soon form the best linebacker duo in the NFL, if they didn't already last season. Jack's ankle injury from the playoffs doesn't seem to be an issue.
