As Trotter points out, the Raiders saw tangible progress on the defensive line in Buckner’s year on the job.

Raiders’ progress under Buckner

The Raiders improved from last in the league with 13 sacks in 2018 to 24th with 32 in 2019. They also improved from 30th to eighth against the run, where they allowed just 98.1 yards per game on the ground last season, an improvement of better than 40 yards on average.

Buckner, 48, played in the league as a defensive lineman for 12 seasons from 1994 to 2005 and has worked as a defensive line coach in the NFL since 2013, where he started with the Arizona Cardinals. He spent 2018 on the Tampa Bay Buccaneers staff before joining the Raiders last season.

Buckner surprised by firing

Gruden reportedly told Buckner that his performance wasn’t the reason for the firing.

Marinelli, 70, was the head coach of the Detroit Lions from 2006 to 2008 and has spent the last six seasons as the Dallas Cowboys defensive coordinator.
