The Green Bay Packers fired head coach Mike McCarthy following a shocking 20-17 home loss to the Arizona Cardinals on Sunday, following long withstanding rumors that he and star quarterback Aaron Rodgers were no longer on the same page.

Though Rodgers has been able to carry flawed Green Bay teams to the playoffs in the past, 2018 has been an exception. The Packers haven't supplied Rodgers with enough talent on offense, and McCarthy's play calls were widely criticized throughout the 2018 season.

But apparently, Rodgers and McCarthy's disagreements on offense date back to the 2012 season. ESPN NFL analyst Jeff Saturday - who played for the Packers in 2012 - revealed some daunting information about Rodgers' distrust in his former coach.

"When you'd be in the huddle, and Mike McCarthy would make the play call, you could see Aaron's frustration," Saturday said on ESPN, via Bleacher Report's Mike Freeman.

2018 is the first time since he became the Packers' starter in 2008 where Rodgers doesn't look like an MVP candidate. That obviously isn't on the fault of No. 12, who's had to deal with constant changing on the offensive side of the ball and questionable play calling from the offense.

The Packers are on the verge of missing the playoffs in consecutive seasons for the first time since 2005-06. The bar is always set high in Wisconsin, where Packer fans expect championship contention every year.

Firing McCarthy is the first major change the Packer front office is making. The focus this offseason will be on finding enough playmakers for Rodgers on the offensive side of the ball.

What This Means

If Rodgers' tension with McCarthy truly dates back to 2012 (perhaps even sooner), the two men certainly did a good job of hiding it. Both of them put on smiles and at least acted as if they were on the same page.

For the Packers, they need to ensure that Rodgers' next head coach is an offensive guru who can build an offense around the talents of No. 12. He's now 35 years of age, and there are only so many prime years left in the two-time MVP.
