Green Bay — The Green Bay Packers took 53 players, 23 coaches and an army of staffers with a game plan and planeload of equipment to Arizona for Saturday's game.
They also take some intangibles, rooted in powerful psychological theory, that they may not even realize.
Self-efficacy, verbal persuasion, imaginal experiences — none are the topics of a typical post-game news conference. But these mental tools, which extend far beyond the world of sports, go a long way toward explaining why the Packers, to a man, think they have a shot at beating Arizona in an NFC divisional playoff game Saturday night.
