Broncos' Running Back Depth Crisis Opens a Temporary Market Edge

The Broncos worked out three undrafted running backs on Tuesday—Jaden Nixon, Sam Scott, and Marcus Yarns—a move driven by the sudden unavailability of RJ Harvey and J.K. Dobbins. Harvey went down in Week 1 and has returned only to limited practice duty. Dobbins suffered his hamstring injury mid-game Sunday against Jacksonville. Head coach Sean Payton offered qualified optimism about both players' prospects, but the team's actions tell a different story: they're preparing for a scenario in which neither is available for meaningful work this week or next.

The depth chart below Harvey and Dobbins is thinner than it looks. Third-round rookie Jonah Coleman remains the only healthy back with a clear offensive role, though Payton acknowledged all three starters can "handle a majority of the carries." Tyler Badie, a reserve on the 53-man roster, recorded two catches for 28 yards in Week 2 and profiles as a pass-catching complement rather than a primary runner. Practice squad depth consists of Cody Schrader, who has accumulated a grand total of 16 NFL snaps over two seasons with the Rams. The trio Denver auditioned—Nixon from Western Michigan, Scott from Wyoming, Yarns from Delaware—bring zero regular-season experience to an NFL offense mid-season. Nixon did receive a full physical, signaling the Broncos view him as a potential emergency option.

The betting implication hinges on carry distribution and total volume over the next 1–2 weeks. If Harvey and Dobbins remain sidelined, Coleman will command 15–20 carries per game, a workload far above his preseason projection. That concentration of touches translates directly into rushing yards props for Coleman and elevated team rushing totals—Denver will lean harder on the ground game out of necessity. Conversely, the Broncos' passing game props face compression: defenses can stack the box against a backfield led by a rookie, forcing quarterback pressures and reducing explosive play opportunities. The market has not yet recalibrated passing yard totals downward to reflect this shift, particularly if the injury news broke late or wasn't priced into opening lines.

The durability question cuts deeper than a one-week problem. Both Harvey and Dobbins carry documented hamstring injury histories—the kind of soft-tissue damage that lingers. Even if one returns to practice this week, snap counts and carry totals will be managed conservatively through mid-October. Coleman's rushing line could sustain elevated volume for 3–4 games, not just one. The Broncos' decision to evaluate fresh bodies signals they expect to weather a longer absence than typical hamstring injuries, which average 2–3 weeks of missed time. Yards gained in a thin backfield context matter more: Coleman's yards-per-carry efficiency may actually improve as defenses adjust to a more predictable offensive identity.

For prop bettors, the edge exists in Coleman rushing yards—take overs on any line below 80 yards for the next two weeks—and in fading Broncos passing yard totals if they opened at season averages. The passing compression is temporary but real. Defenses will attack a backfield dependent on a rookie, and even a healthy offense can only absorb so much disruption before efficiency declines. The three tryouts Denver brought in are noise; what matters is that both known options are damaged goods, and that changes the risk/reward of every play-caller's options.
