I have always held a special regard for Packers who came up big at crucial moments in Bears game.
Some, like Rodgers & Favre, did it, of course, on a regular basis.
Others had multiple moments : Sam Shields, Randall Cobb, Jordy Nelson.
Still others were a kind of one-hit wonders : Johnny Jolly, BJ Raji, Don Majkowski, Chester Marcol, Adrian Amos.

Who am I forgetting?
