You have to go back to 1940 to find a span of futility similar to the one Pittsburgh's offense is experiencing this season. The Steelers were blanked during the first half of Sunday's Week 16 matchup against the Chiefs. It marked the fifth consecutive game they failed to score a touchdown in the first half. 

The Steelers didn't score a single point in the first half against a Chiefs defense that has been one of the NFL's hottest units during the second half of the season. Pittsburgh, which trailed 23-0 at halftime, gained just 109 total yards while controlling the ball for less than 10 minutes. The Steelers' only significant drive of the first half ended with Chris Boswell's missed 36-yard field goal. 

Pittsburgh's young offensive line is one of the major reasons for the unit's struggles. The line has often struggled to open up holes for rookie running back Najee Harris, who entered Sunday's game with a 3.6-yards-per-carry average. The Steelers have also struggled at times to get into an early rhythm behind first-year offensive coordinator Matt Canada. 

The Steelers' offense has at times overcome slow starts with strong finishes. But those slow starts have also contributed to the Steelers' underwhelming 7-6-1 record entering Sunday's game. Given their struggles on offense, expect Pittsburgh to focus on that side of the ball during the early stages of next year's draft. But until then, the Steelers will try to make due with their current collection of players for the final stages of the 2021 regular season.
