Reflexively, Justin McCray dropped to his knee in a quick prayer. It’s what teammates do when comrades fall. Jason Spriggs, the Green Bay Packers' second-year right tackle, was down on the field writhing in pain. He’d soon be carted to the locker room, scrapping an entire week of preparation on the right side of the Packers' offensive line. All it took was one snap for their plan to dissolve. Which is why McCray could’ve used some beseeching on his own behalf, too. At the onset of Saturday night’s 16-0 loss to the Minnesota Vikings, everything McCray thought he’d see against one of the NFL’s top defenses changed. McCray spent four days anticipating a spot start at right guard. One play. One injured teammate. And McCray was blocking again on the perimeter. “I don’t know if people understand how hard that is,” center Corey Linsley said, “and how much discipline and focus it takes. Not only right then, but during the week. Because Justin is going from a different position. Not only is he making a spot start, but he’s moving to a different position.” It wasn’t nearly enough for the Packers to win. No, their patchwork offense — no Aaron Rodgers, no Davante Adams, even Jordy Nelson left with a shoulder injury midway through — was shut out at home for the second time this season. It’s the first time that’s happened in 11 years. Add another milestone to a season that will end without a playoff bid for the first time since 2008.
