As the jubilant Vikings spilled into their locker room at Lambeau Field the night of Jan. 3, team staffers tossed them championship hats and T-shirts. ¶ While safety Harrison Smith and other defenders, exhausted after playing most of the second half as the Vikings held off a relentless Packers rally, collapsed into folding chairs, all of the wide receivers posed for a selfie. ¶ At one point, the linebackers sneaked back out onto the tundra for an old-fashioned group photo with Chad Greenway, not knowing if it was his last hurrah. ¶ But the lasting image of the night was coach Mike Zimmer, sporting a wide grin and a gray NFC North champions hat, with his feet kicked up at the front of the team bus before it pulled out of Lambeau toward the local airport.
