It was 2013 all over again for Nick Foles and the Philadelphia Eagles, as the quarterback channeled his younger self to light up Minnesota’s vaunted secondary in a 38-7 victory in the N.F.C. Championship game.

Foles’s huge performance ended the Vikings’ season and catapulted the Eagles to Super Bowl LII, where they will face the daunting task of taking on Tom Brady and the New England Patriots.

Foles, who had looked like a potential franchise quarterback in a stint as Philadelphia’s starter in 2013, was thrust back into a starting role following Carson Wentz’s devastating knee injury in Week 13.
