The issue is more than DC Joe Barry, it's D-Line coach, the linebacker's coach, the OC who was a very good O-line coach and the HC who over the last two years has shown to be more like McCarthy in his last two seasons. Stubborn, unable to adjust, and unwilling to listen.
Not long ago Mark Murphy made himself the lord of Gutey and LaFleur having them report direct to him.
In my opinion Murphy needs to go, along with the entire coaching staff with the exception of Clements, who's done a good job of working with Love.
I personally would like to see Murphy replaced with John Schneider, and then raid the 49er or Texans D-Staff for a new Head Coach.
Compare what DeMeco Ryans has done with a young roster in Houston, versus what LaFleur has done this year. While Houston has lost games, they have not been out coached, game after game, after game.
Other teams keep doing the same things to the Packers knowing we will not adjust to stop them. What does LaFleur do on Offense, stop doing what was working (running Jones, etc) and get cute with the play calling. He is more McCarthy 2017-2018, than the next best coach. He is the new Marty Shottenheimer, king of the regular season and unable to get the W in big games. It's why the Chargers fired Marty after a 14-2 season. We need to not do what San Diego did and wait too long to move on.
