Denver Post Broncos writer Parker Gabriel posts his Broncos Mailbag weekly during the season and periodically during the offseason. Click here to submit a question. A couple of weeks ago, Bo Nix had a game where he couldn’t hit the side of the proverbial barn.

In his second year as Denver Broncos head coach, Sean Payton delivered the club's first winning season since 2016 and its first playoff berth since 2015. The Broncos went 10-7 in a season where the NFL at large and the oddsmakers predicted they'd be cellar-dwellers yet again.
