FWIW, I remember reading at the time right after hiring Joe an interview with Aaron Rodgers where he attributes much of his football succcess and personal development to Philbin. When the best QB in the league who's known for speaking his mind, being occasionally headstrong and petulant... and not mincing words waxes so enthusiastically about Philbin's influence, IMO, you cannot find a better testimonial regarding his leadership.
Wisdom from a "QB Whisperer::
"No we have our FRANCHISE QB and I want to keep him rather than get 2 guys who may or may not be productive NFL players.
Palmer's situation is different and if I had my choice between Palmer and buttfumble, I'd take buttfumble"
