Pre-draft Jack was one of 39 linebackers to attend the
NFL Scouting Combine in
Indianapolis, Indiana. He was limited to the
bench press due to his knee and finished tied for 13th in the bench press among all participating linebackers. On March 10, 2016, Jack attended UCLA's
pro day and performed the
vertical jump,
broad jump, and positional drills. His vertical jump would have finished eighth among all linebackers at the combine and his broad jump would have finished fourth. Team representatives and scouts from all 32 teams attended to scout Jack and meet with him, including head coach
Hue Jackson (
Cleveland Browns) and general managers
Doug Whaley (
Buffalo Bills) and
Les Snead (
Los Angeles Rams). Throughout the draft process, Jack attended private visits and workouts with multiple NFL teams, including the Jacksonville Jaguars,
Miami Dolphins,
Chicago Bears,
New Orleans Saints,
San Francisco 49ers,
Atlanta Falcons, and
Oakland Raiders. On April 14, 2016, he returned to Indianapolis to undergo another physical to check on his knee and evaluate his recovery progress. Prior to the draft, Jack was confident he could play immediately, but admitted that his knee had degenerative aspects which could require
microfracture surgery in the future. At the conclusion of the pre-draft process, Jack was projected to be an early first round pick by NFL draft experts and scouts expected him to be a top ten pick. He was ranked the top linebacker prospect in the draft by
Sports Illustrated, ESPN, and NFL analysts
Charles Davis,
Mike Mayock,
Lance Zierlein, and
Daniel Jeremiah. Jack was also ranked the top overall player in the draft by
ESPN, the second best overall player by NFL analysts Daniel Jeremiah and Lance Zierlein, and the third best overall player by NFL analyst Charles Davis.
Jacksonville Jaguars 2016 The
Jacksonville Jaguars selected Jack in the second round with the 36th overall pick in the 2016 NFL draft. The Jaguars traded their second (38th overall) and fifth round (146th overall) picks in the 2016 NFL draft to the
Baltimore Ravens in order to move up two spots to 36th overall and draft Myles Jack. His fall out of the first round was widely attributed to concerns over his knee. Jack was the fifth linebacker selected in 2016. On May 13, 2016, the Jaguars signed Jack to a four-year, $6.33 million contract that includes $3.54 million guaranteed and a
signing bonus of $2.80 million. Throughout
training camp, he competed against veteran
Dan Skuta to be the starting strongside linebacker and also took reps at middle linebacker. Head coach
Gus Bradley named Jack the backup outside linebacker behind veterans Dan Skuta and Telvin Smith to begin the regular season. He made his professional regular season debut in the Jaguars' season-opening 27–23 loss to the
Green Bay Packers. The following week, Jack recorded his first solo tackle on Chargers' running back
Melvin Gordon after Gordon caught an 11-yard pass by
Philip Rivers. After tackling Gordon again on the following play, Jack finished the Jaguars' 38–14 loss at the
San Diego Chargers with two solo tackles. On October 2, 2016, Jack earned his first career start at strongside linebacker after

Tyrod Taylor during the Jaguars' 28–21 loss to the Bills. Head coach Gus Bradley was fired after their Week 15 loss to the
Houston Texans due a nine-game losing streak and a 2–12 record. Assistant head coach/offensive line coach
Doug Marrone was named interim head coach for the last two games of the season. Jack finished his rookie season in 2016 with 24 combined tackles (18 solo), two pass deflections, and was credited with half a sack in 16 games and ten starts.
2017 On January 9, 2017, interim head coach Doug Marrone was elevated to full-time head coach and opted to retain
Todd Wash as the Jaguars' defensive coordinator. On April 18, 2017, it was announced by the Jaguars' coaching staff that Myles Jack would enter organized team activities as the starting middle linebacker and Paul Posluszny would take over the starting strongside linebacker role previously held by Jack and the recently departed
Dan Skuta. Throughout training camp, Jack made the transition to middle linebacker with the assistance of teammate Paul Posluszny. Jack reverted to his strongside linebacker position after he struggled to adjust to his new role and had difficulty performing the required duties during the Jaguars' first preseason game against the
New England Patriots. Head coach Doug Marrone named Jack the starting strongside linebacker,
Telvin Smith the starting weakside linebacker, and
Paul Posluszny the starting middle linebacker to start the regular season. He started the Jaguars' season-opener at the Texans and recorded a season-high 14 combined tackles (eight solo) during their 29–7 victory.

Telvin Smith who had 102 combined tackles. The Jaguars finished first in the
American Football Conference (AFC) South with a 10–6 record in their first season under head coach Doug Marrone. On January 7, 2018, Jack started his first career playoff game and recorded six combined tackles, two pass deflections, and a sack in a 10–3 victory over the Bills in the AFC

Divisional Round. On January 21, 2018, he collected seven combined tackles during the Jaguars' 24–20 loss at the Patriots in the
AFC Championship. He was a part of a controversial play in the fourth quarter that occurred after he forced a fumble by Patriots' running back
Dion Lewis and recovered it. Jack was returning it for a defensive touchdown that would have put the Jaguars' up 26–10 against the Patriots, but had the play blown dead by the referees who had seen Jack was down after recovering the fumble.

New York Giants, Jack recorded a 32-yard pick six off of
