MINNEAPOLIS — Stefon Diggs jumped up and down on the Vikings’ sideline, screaming in elation as “Enter Sandman” blared out of the speakers inside U.S. Bank Stadium with just over 10 minutes to play in the fourth quarter.

Moments before, Diggs had caught a 54-yard touchdown from Kirk Cousins on a route the quarterback noted is only hit “once a decade” to breathe life into a Vikings team that was on the verge of losing to the Denver Broncos in befuddling fashion after entering Week 11 as a double-digit favorite over their last-place AFC West opponent.
