Since Lock assumed the starting role ahead of Week 13, the Broncos have found success that has eluded the team for much of the season.

Consider this: In 11 games without Lock under center, Denver earned just four wins and averaged just 15.9 points per game.

Before Lock took over, the Broncos ranked 27th in total offense, 29th in scoring offense and 29th in passing offense. They allowed the 25th most sacks in the league, had the third-worst third-down offense and were 27th in the red zone.

The above stats illustrate an uncomfortable reality for a Broncos offense that struggled as Denver lost five one-possession games and broke the 23-point mark in just three games.

Lock, though, has given the Broncos' offense a jolt.

In four starts, Lock has led Denver to at least 23 points in three of the games. He has completed 64.8 percent of his passes and been sacked three times. His completion percentage would rank 13th in the NFL among qualifying quarterbacks, and his sack rate would rank first.

He has also thrown six touchdowns after the Broncos had nine passing touchdowns in their first 11 games.

The team's third-down conversion rate (44.9 percent) and scoring offense (22.8 ppg) took jumps too; they would rank fifth and 17th, respectively.

Those numbers include a Week 15 game in the snow in Kansas City in which the Broncos mustered just three points in a loss. Exclude that performance, and the offense's numbers look even better.

It's early in Lock's career, but these results have his teammates believing in what could be next.

"He's going out there and he's proving himself," running back Phillip Lindsay said. "He's calm, cool and collected, and he understands what he needs to work on and what he's good at. The thing is, he can move out the pocket and he's a game-changer. He can make plays. We've got to ride around him, and help him out by getting open.
