"League sources" i.e. Green Bay Packers front office executives.
It is really surprising to me how antagonistic they seem to have been with Rodgers. I get that Rodgers is a little prickly, but how they've handled their transition, going back to the drafting of Jordan Love, seems ridiculously short sighted.
These days, if you are taking a QB in Round 1, you better expect that person to play right away. Instead, they wasted a chance to get a QB in his prime one of several talented offensive players still on the board (Tee Higgins and D'Andre Swift included).
Say what you will about Karen Rodgers, but Green Bay really botched this transition. A Hall of Fame player deserves better than this.
