Jack has not missed a game through his three seasons with the Jaguars, starting 42 games, including each of the past 34 regular season contests. He has three playoff games in his career as well, recording 16 tackles, one sack, one interception, and one fumble recovery in those contests. For his career, the linebacker has 219 tackles, five sacks, two fumble recoveries, and one interception.
The deal he got is just smaller than the one the Dallas Cowboys gave Jaylon Smith last week, which was a five-year extension that is worth $64 million, with $35.5 million in guaranteed money. As a rookie, he played all three linebacker positions for the Jaguars, but became the middle linebacker permanently in 2017. He has led the Jaguars to be one of the most powerful defenses in the league, which even led them to the AFC Championship Game two seasons ago. If they want any chance of getting back to that kind of success, they knew Jack had to stick around.
