After hiring Brian Duker as his defensive coordinator, Jets HC Aaron Glenn finalized his defensive staff with four additions -- linebackers coach Ben Bolling, safeties coach Ryan Slowik, defensive assistant/nickels coach Ronald Booker and defensive assistant Collin Bauer.
Bolling, 32, was on the Houston Texans' defensive staff the past five seasons. After a four-year run as defensive assistant, he was promoted to assistant linebackers coach in 2025. He got his coaching start at Campbell University as a defensive assistant/safeties coach in 2016-18 before transitioning to wide receivers coach and offensive recruiting coordinator in 2019-20. Bolling played WR at Campbell, redshirting in 2011 before hauling in 100 receptions for 1,329 yards and 8 TDs in 44 games from 2021-15. The North Carolina native lettered in three sports at Knightdale HS and became the school's all-time leader in passing yards (3,557), career touchdowns (40) and career total yards (5,191).
Most recently with the Dolphins, Slowik, 45, worked closely with Duker as defensive backs coach/passing game specialist in 2024-25. He also held the titles of senior defensive assistant (2022) and outside linebackers coach (2023) in Miami. A native of Gainesville, FL, Slowik left the Arizona Cardinals where he served as the defensive quality control coach (2009-11), the outside linebackers coach (2012) and defensive assistant/assistant defensive back coach (2013-14) when Todd Bowles also left the Valley of the Sun to take over as HC of the Jets. For one season in 2015, Slowik, was the Green & White's assistant D-line coach when the unit finished second in rushing yards allowed (83.4 per game) and allowed the third fewest yards per carry (3.5 yards per) in the NFL while logging 39 sacks.
Slowik began his college playing career as a safety for Youngstown State (1999-2000) before transferring to Wisconsin-Oshkosh (2001-03) where he was a strong safety. Upon the end of his playing career, he moved 54 miles north to Green Bay, joining the Packers as a personnel scout. He returned to Oshkosh in 2004 for one year as the Titans' assistant secondary coach
He joined the Denver Broncos as a defensive assistant (2005-06) -- where his father Bob was the defensive backs coach -- the assistant special teams coach (2007) and assistant defensive backs coach (2008). Arizona was his next stop for five seasons before his one season with the Jets. After a season in Cleveland (2016) as outside linebackers coach, then a year as the University of Tennessee's defensive analyst (2017), and another a year out of the sport, he was then the assistant coach at the Webb School of Knoxville, TN.
Booker just completed his fifth season with the Arizona Cardinals and third as a defensive quality control coach after working two years (2021-22) as a defensive assistant. He spent two years with Arizona as a Bill Walsh Coaching Fellow (2020-21) prior to being hired full-time. Booker, a Memphis, TN, native, was a defensive back and special teams stalwart at Rhodes College before serving as safeties coach, defensive backs coach, wide receivers coach, special teams coordinator and strength and conditioning director at his alma mater from 2014-18. He then spent two seasons at Pitt where he was an offensive graduate assistant and worked with the team's wide receivers.
Bauer comes to the Jets from the UFL where he was the Michigan Panthers defensive coordinator and defensive line coach (2024-25) and defensive line coach in 2023. Prior to that, Bauer worked on the college level at Towson State from 2018-22 as defensive line coach and recruiting coordinator, at Rutgers as defensive quality control (2017) and defensive line graduate assistant (2016), at Maryland as a defensive line graduate assistant (2014-15) and at the Citadel as a defensive backs graduate assistant (2013). He began his career as a student assistant at Towson from 2010 until graduating in 2013 with a Bachelor of Science in Social Sciences. He earned his Masters of Real Estate Development Certificate from the University of Maryland in 2016.
