The Broncos’ route to their first playoff berth since 2015 took them through highs and lows from coast to coast. They lost in Seattle and won in Tampa. They spent a week in West Virginia and played Thursday night on the road twice. They ripped through Sean Payton’s old division, sweeping four games against the NFC South. They won three or more straight twice, lost back-to-back twice and ultimately clinched a spot in the AFC Wild Card round on the final day of the regular season. Along the way, Bo Nix and company turned a low-expectation season into a 10-win success story.
