The Denver Broncos' offense is close to making the Tim Tebow-era teams look prolific.

The Broncos 18.8 points per game are their fewest since 1992 when John Elway missed four games with a shoulder injury. Denver's 4.91 yards per play is the team's fewest since 2001 when Terrell Davis played just eight games in his final season. And the 214.9 passing yards per game is the worst since the 2011 Tebow-led team.

At least that 2011 team won games by running the ball, leading the league with 164.5 per tilt. The 2017 version of the Broncos offense has struggled to even do that for long stretches during their four-game losing streak. In three of the past four losses, Denver failed to gain 70 yards rushing. In Sunday's blowout loss to the stingy Eagles, they put up a season-low 35 rushing yards.

In order to hide a shaky quarterback situation, running back C.J. Anderson knows the team must be better on the ground.
