The Denver Broncos backfield presents a compelling fantasy football decision as JK Dobbins and RJ Harvey prepare to debut in Sean Payton’s revamped offensive system.
Both running backs bring different skill sets to the table as they face a vulnerable Tennessee Titans defense in what projects as a favorable matchup. The question facing fantasy managers centers on which back offers better Week 1 value in what appears destined to become a productive timeshare.
JK Dobbins Fantasy Outlook
JK Dobbins enters Week 1 as the official starter on Denver’s depth chart, benefiting from Sean Payton’s tendency to defer to veteran experience early in the season. Despite being signed to a one-year deal during the offseason, the veteran has positioned himself to handle primary duties against Tennessee.
The former Baltimore Ravens and Los Angeles Chargers back rejuvenated his career in 2024, accumulating 905 rushing yards and nine touchdowns on 195 carries while averaging 4.6 yards per carry. His performance ranked in the top 10 among starting running backs in yards after contact per attempt and broken tackles, demonstrating his physical running style.
Dobbins’ pass-catching ability provides additional fantasy value, earning a respectable 10.2% target share last season with Los Angeles. Payton’s offensive system historically features running backs heavily in the passing game, with Denver leading the league last season with a 32% running back target share despite their lack of talent.
The veteran’s experience in pass protection gives him an edge over Harvey in third-down situations, particularly valuable in Payton’s system that emphasizes running back involvement. His familiarity with NFL-level pass blocking schemes makes him the safer option for obvious passing situations early in the season.

Dobbins projects as the favorite for goal-line opportunities based on his size and proven red zone production. Despite the timeshare concerns, his 4.6 yards per carry efficiency and ability to handle volume make him a legitimate RB3/flex option.
RJ Harvey Fantasy Outlook
Meanwhile, RJ Harvey brings explosive potential to Denver’s backfield as the second-round pick looks to carve out an immediate role alongside Dobbins. The UCF product impressed throughout training camp and preseason action, flashing the big-play ability that convinced the Broncos to invest significant draft capital.

The rookie’s 4.4 speed and compact 5’8″, 205-pound frame create a dynamic presence that Payton can utilize in creative ways. His college production included a 9.4% target share in his final season at UCF, suggesting he possesses the pass-catching skills to thrive in Denver’s system.
Harvey has demonstrated impressive vision and decision-making for a rookie. His background as a former quarterback provides additional football IQ that helps him process defensive alignments. His ability to make quick cuts and find rushing lanes has impressed coaches throughout the summer.
Payton’s history of developing versatile running backs suggests Harvey could see designed touches rather than traditional carries and checkdowns.
However, Harvey’s pass protection remains a work in progress, limiting his third-down opportunities until he demonstrates NFL-level blocking ability. His rookie status and need for continued development suggest he may need to wait a bit before becoming the lead man in this backfield.
Should You Start Dobbins or Harvey This Week?
The matchup against Tennessee provides an extremely favorable environment for both Broncos running backs. The Titans allowed 133.9 rushing yards per game and the 10th most fantasy points to running backs last season, creating opportunities for productive performances.
Denver enters as eight-point home favorites, suggesting a positive game script that should benefit the ground game throughout the contest. The Broncos’ emphasis on establishing the run under Payton makes both backs viable fantasy options.

This represents a rare situation where both running backs from the same backfield merit fantasy consideration, similar to successful committees like Mark Ingram and Alvin Kamara with the Saints back in the day or Jahmyr Gibbs and David Montgomery in Detroit. The complementary skill sets and favorable matchups create paths to production for both players.
Fantasy managers can trust both Dobbins and Harvey in Week 1 lineups, though the veteran represents the better bet to secure more touches and goal-line work. Payton’s preference for veteran leadership early in the season gives Dobbins an edge in what projects as a 60-40 or 55-45 split.
Harvey offers the most long-term upside and was drafted significantly earlier in fantasy leagues, but Week 1 expectations should favor Dobbins based on his starting role and pass protection advantages. The rookie’s time will come as the season progresses, but patience may be required initially.
