It's virtually impossible for an NFL team to win a game today with only 10 points, but the Denver Broncos managed to do that this year. They have scored fewer than 20 points three times this year and have won all of those games.
It's clear that the defense is special, and the unit is good enough to appear in the Super Bowl this year. What we have to see from this team going forward is the offense to simply figure it out and take a step in the right direction.
And it's not just one thing holding this offense back.
