On Tuesday, two days after the McCarthy firing, the Packers also fired associate head coach Winston Moss - on the same day he tweeted a message calling for leadership within the organization and for someone to hold Rodgers accountable.
"It's never about one thing", Philbin said Wednesday. "It wasn't an easy decision. I just think the fit right now isn't where it needs to be".
The Packers released a brief statement confirming Moss' dismissal on Tuesday night. The 52-year-old coach had sent out a tweet earlier in the day on Tuesday that was perceived to be critical of both McCarthy and the franchise's star quarterback, Aaron Rodgers.More news: Funeral for former President George H.W.

"Again, I'm not going to really comment on the tweet", Philbin said. And another advantage, quite honestly, of making the change now rather than after the season is this gives us an opportunity to see Joe as our head coach for four games, see how the team responds and see how the coaches and others respond.
New England Patriots offensive coordinator Josh McDaniels deflected questions about a potential head coaching gig, but he didn't rule out the possibility of moving up the ranks.
Philbin said defensive assistant Scott McCurley would take over for Moss as linebackers coach. But media scrutiny became more intense in recent weeks of the relationship behind the scenes, and Moss, of course, had a front-row seat to the player-coach interaction for the duration of McCarthy's tenure.
