The Broncos’ second-year quarterback was tied in knots by Vic Fangio’s Eagles defense for three quarters. Then, Nix came alive — with a little help from Denver’s marquee free-agent additions on offense.

The Broncos began turning the tide when they turned to JK Dobbins. The veteran running back began finding holes in Philadelphia’s defense in the third quarter and began the fourth quarter with his fourth rushing touchdown of the season, cutting the lead to seven points. On Denver’s next drive, Nix hit tight end Evan Engram on a 18-yard pass up the seam that lit the fuse on another touchdown drive. It ended with Engram, who had failed to make an impact on Denver’s offense through four games, scoring his first touchdown with the Broncos.

Broncos coach Sean Payton decided to go for two after the Engram touchdown pulled Denver to within one point, and Nix hit Troy Franklin in the front of the end zone to give Denver the lead. Nix and the Broncos converted three straight third downs in the fourth quarter.

Nix had come close to authoring signature road wins before, only to fall short. On Sunday, he finished the job.
