Although the Ravens' offense is ranked second in the NFL in total offense with 424 yards per contest and fifth in scoring offense with a 30.3 average, they've actually overcome a series of slow starts this season. The Ravens have been outscored 20-17 in the first quarter, outscoring opponents, 121-83, through four games. The second quarter and third quarter have been the Ravens' most effective quarters with margins of 40-24 and 38-23, respectively. The Chiefs appear vulnerable early in football games, failing to match the tempo of quarterbacks like Matt Ryan and Philip Rivers. The Chiefs haven't led in a game all season with their lone win coming in a 27-24 overtime victory over the New Orleans Saints. In the first quarter, the Chiefs have been outscored, 41-6. And halftime adjustments haven't fared well for the Chiefs, either. They've been outscored 42-17 in the third quarter. The only advantage the Chiefs have in scoring has been in the fourth quarter where they've built an edge of 39-16 in scoring margin. The Ravens can definitely try out their deep passing game where they lead the NFL with 24 completions of 20 yards or higher.
