During the 2017 season, Pettine worked as a consultant for the Seattle Seahawks.
The Browns went just 10-22 under Pettine, and his time as a defensive coordinator in the AFC East was something of a mixed bag.
Pettine, 51, served as defensive coordinator for the Jets from 2009-12 before spending the 2013 season in the same position with the Bills.
McCarthy also apparently wanted to speak with Los Angeles Chargers defensive coordinator Gus Bradley, who received a contract extension to remain with the Chargers. His defenses with the Jets were first, third, fifth, and eighth, and his Bills defense was 10th in his lone season in Buffalo.
It was reported earlier in the week that Philbin was interviewing with his former team and NFL Network's Ian Rapoport reported Wednesday that Philbin will be the new offensive coordinator.
That should end soon as they hire a guy who loves to bring pressure and who's defenses regularly finish in the top ten. His defenses all finished in the top 10. Additionally, Pettine was a coaching assistant with the Baltimore Ravens (2002-2003), as well as Baltimore's assistant defensive line coach (2004) and outside linebackers coach (2005-2008).
Pettine the job over Packers assistants Darren Perry, Joe Whitt Jr. and Winston Moss.
