I suppose they earned it, sort of. On the 1st Green Bay touchdown drive the refs missed a blatant hold on 3rd down that allowed Green Bay to get the 1st Down. Troy Aikmen remarked that he was amazed it wasn't called. If Green Bay has to punt there they don't get there 1st and immediately following 2nd touchdown and it is a totally different game. Pittsburgh outscored Green Bay after those two touchdowns.
Still the Steelers had the chance to win the game and they didn't get it, so congratulations Cheeseheads. The worst part: Who believes this is Aaron Rodgers last Super Bowl Game?
