An all-time cornerback combination for the Miami Dolphins is reunited on new coach Mike McDaniel’s coaching staff.

Patrick Surtain is joining the Dolphins as a defensive assistant, according to a league source. The news on Friday, first reported by Fox Sports 640, comes days after Miami hired his Dolphins teammate Sam Madison as cornerbacks coach and pass game specialist on Wednesday night.

Surtain and Madison formed one of the league’s greatest cornerback duos between the late 1990s and early 2000s on fierce Dolphins defenses that constantly kept the franchise in playoff contention.

Surtain was a three-time Pro Bowl selection and once made first-team All-Pro during his seven seasons as a Dolphins player from 1998 to 2004. He had 29 interceptions in that time and added eight more in his final four NFL seasons with the Kansas City Chiefs.

Madison was a four-time Pro Bowler and two-time All-Pro with the Dolphins. He had 38 career interceptions — 31 which came with Miami in nine seasons from 1997 to 2005.

Surtain was most recently the head coach at South Florida high school football powerhouse American Heritage, where he won three state championships in six years as head coach since 2016.

Surtain’s son, Patrick Surtain II, whom he coached in high school, just completed his rookie season with the Denver Broncos after an accomplished college career at Alabama. Surtain II had four interceptions as a rookie in Denver.

Surtain Sr. goes from coaching in high school straight to the NFL. In 2018, as his son was heading to Alabama, he interviewed with Crimson Tide coach Nick Saban for a spot on the coaching staff but ultimately remained with the Plantation high school, delivering another state title in 2020 after winning back-to-back in 2016 and 2017.

Madison has also coached at a local high school powerhouse — St. Thomas Aquinas as defensive backs coach, where he was on the same staff as Dolphins Hall of Famer Jason Taylor — but he had an assistant coaching role with the Kansas City Chiefs the past three seasons, including a Super Bowl victory in 2019.

The Dolphins still presumably have an opening for a primary defensive backs or safeties coach with Surtain on as a defensive assistant.

Madison’s job replaced former cornerbacks coach Charles Burks, who left for an opportunity with the Cincinnati Bengals.

Madison and Surtain will have their hands on a talented Miami secondary that includes the team’s two highest-paid players in cornerbacks Xavien Howard and Byron Jones and an upstart young safety combination in rising second-year player Jevon Holland and Brandon Jones, who will enter his third NFL season in 2022.
