National writers increasingly have been pointing to Aaron Rodgers as a main source of Green Bay's struggles, but let's add another more interesting voice to that mix: former Packers and Vikings receiver Greg Jennings.

Jennings — who enjoyed the best years of his career with Rodgers as his QB — had some pretty frank words about his former teammate in a recent appearance on the FS1 show "Undisputed."

Jennings said receivers in Green Bay always have been blamed while Rodgers has been praised.

"He has never really had to self-assess and never really had to self-reflect," Jennings said. "Everyone's always projected it somewhere else. Now the focus is on him. They will not win if he does not play better.

"Every team walking into Lambeau now believes they can win. Why? Because they see Aaron Rodgers not playing the way they've seen him play in the past."
