Philbin spent nine seasons (2003-2011) as a Packers assistant coach, including the last five as coach Mike McCarthy's offensive coordinator.
Here's a sampling of some of the reaction:

Want to wish Joe Philbin and his family luck in whatever their next step is.. GREAT MAN, and one of my favorite coaches I've worked with

From former Packers tackle Mark Tauscher:
Joe Philbin is a fine coach, but an even better man. He is the type of coach I would love for my kids to learn from
