The Packers have discussed their defensive coordinator vacancy with Kris Richard, as Tom Silverstein of the Milwaukee Journal Sentinel tweets. He’s the latest candidate to surface for the job, joining Chargers assistant Joe Barry, Rams safeties coach Ejiro Evero, and Washington defensive backs coach Chris Harris on the list. 
Richard was one of the architects of the Seahawks’ famed Legion of Boom. After managing Seattle’s defensive backs, he was elevated to defensive coordinator in 2015. The ‘Hawks parted ways with Richard at the end of the 2017 season, prompting him to move on to the Cowboys as their DB/defensive passing game coach.
He didn’t get to stick around for Mike McCarthy‘s staff, however, and he spent the 2020 season out of football. Still, it wasn’t long ago that Richard was being considered for head coaching jobs and his overall track record is impressive.
Richard, who also interviewed with the Raiders before the hiring of Gus Bradley, would take over for Mike Pettine.
Other sources indicate Richard was fired as Seattle’s DC for being “too aggressive” and thus giving up the big play too often.
Given what happened at the end of the 1st half in the Packer’s playoff game this doesn’t sound like a good fit.
Wouldn’t you agree, though, that there were times when Pettine wasn’t aggressive enough? Aggressive is good in the right situation, and I’d rather see a team get beat being aggressive than getting a lead, playing conservative, and letting teams come back. If the aggressiveness is applied well, it works. Look at what Tampa did to GB. Pettine’s issue seemed to be more of being aggressive and passive at the wrong times, like man coverage with 6 seconds left in the half.
