Under Colombo, tackle Tyron Smith, guard Zack Martin and center Travis Frederick were among the very best players at their positions in the NFL.

"Continuity is very important, especially between the offensive coordinator and the offensive line coach, that they can be on the same page starting out," Judge said. "One of the challenges of a new staff is getting on the same page and working through some of the differences that maybe we've had from past experiences but making sure we're working to one goal. I'd say with Marc, the deciding factor wasn't his past experience with Jason. The deciding factor was he's a tremendous coach. His body of work as you turn on the tape and watch how his guys play with technique, execution and toughness is ultimately what the deciding factor was."

Wilkerson, 37, is entering his sixth season as an NFL coach and third as the Giants' assistant O-line coach. Prior to joining the Giants, Wilkerson spent three seasons as the Chicago Bears' assistant offensive line coach. He had five years coaching experience at the collegiate and high school levels, as well as three years playing in the NFL.

Dooley, 51, engineered a significant turnaround of Missouri's offense in his first season as coordinator in 2018.

Dooley was the Cowboy's wide receivers coach under Garrett from 2013-17, when Dez Bryant was selected to three Pro Bowls. He also worked with Garrett on the Miami Dolphins staff under Nick Saban in 2005-06. Dooley was the head coach at Louisiana Tech from 2007-09 and Tennessee from 2010-12.

Brown, 32, worked the previous four seasons in Dallas as an offensive assistant/running backs, helping coach Gary Brown and the backs in the coordination of the running game while also serving as a point person for Garrett on research projects and day-to-day operations.

Blick, 35, assisted defensive coordinators Steve Spagnuolo and James Bettcher the last three years and now moves to the offense as quality control coach under Garrett.

Spencer, 49, has been a collegiate defensive line coach for 20 years, including the previous six seasons at Penn State, where he was also associate head coach the past two years. Under Spencer, the Nittany Lions' line was traditionally one of the nation's best. In 2019, Penn State had 45 sacks, which was the seventh-highest total in the country. The previous year, they led the nation with 47 and they were also No. 1 in 2015 with 50. Penn State posted five consecutive 40-sack seasons from 2015-19.

"I've known Sean through the business," Judge said. "The most impressive thing about Sean is the players he's developed through his time at both Vanderbilt (2011-13) and Penn State, among other stops in his career. Sean has a great energy about him, he has great command within a room, his players respond to him, they play hard and they play fundamentally sound."

Sherrer, 46, coached at three Southeastern Conference schools – Alabama, Georgia and Tennessee – as well as South Alabama. He was the Crimson Tide's director of player development from 2010-12, working with Judge the first two years. He moved to South Alabama in 2013 as the defensive coordinator/defensive backs coach, to Georgia as the outside linebackers coach from 2014-17 and then to Tennessee.

"Kevin is just an old ball coach," Judge said. "When I met Kevin, he was coaching at Hoover High School in Alabama. The next year, he was on the staff with us at Alabama. I've watched him progress through his career as defensive coordinator at South Alabama, his time in Georgia, his time in Tennessee. I think Kevin is a phenomenal football coach, and he coaches from the ground up with fundamentals, his players play sound and they play hard."

Bielema, 50, joined the Patriots as a consultant to head coach Bill Belichick in 2018. He coached the defensive line in 2019, when New England's defense was ranked first in the NFL overall (allowing 275.9 yards a game) and sixth against the run (95.5).
