According to the Milwaukee Journal-Sentinel, the Packers aren't "flinching" at quarterback, and the No. 2 job remains Graham Harrell's to lose.
Harrell has attempted zero career passes since coming into the league in 2009, but he'll supposedly enter the season as Aaron Rodgers' primary backup. It would be far from surprising, however, if the Packers pursue a veteran if Harrell is shaky in early preseason action.
