Not too sure about that, Keith Butler does have the defense playing well, but it's the first time in like several years they have been a top ten defense. Teryl Austin is on the staff and coordinated some good defenses in Detroit & was the DC for Cincinnati in 2018 so that would be possible, but Austin has more experience running a 4-3 defense. The rest of their defensive staff includes Jerry Olsavsky inside LB Coach, who has never been a DC, Tom Bradley is the Secondary Coach has plenty of experience and a DC in college, but was part of Joe Paterno's staff at Penn State for 30 years so there is that and their DL Coach Karl Dunbar is somewhat intriguing, great resume as DL Coach, but never has had a whiff as a DC at any level.
