Fantasy football managers spend all summer searching for the next breakout running back, but the real value often comes from the tier no one is excited to draft. Every season, a few RB3s slip past the top 24 only to surge into RB1 territory once talent, opportunity or a shift in usage breaks their way.
This year’s board is full of runners who fit that mold. Below, we highlight three backs with the traits, roles and paths to volume that give them a legitimate chance to outperform their average draft position (ADP) and finish as true RB1s in 2026.

Fantasy Football RB3s With RB1 Potential
David Montgomery (RB – HOU)
David Montgomery enters April as the RB25 according to FantasyPros’ expert consensus rankings (ECR), but his move to the Houston Texans gives him a clearer path to meaningful upside.
Houston traded for him to bring stability to a backfield that struggled to find consistent production, and Montgomery’s history as a steady, high‑volume runner positions him well in an offense that continues to improve. He has shown he can deliver RB1 stretches when given reliable work, and the Texans offer a scoring environment that can raise both his floor and ceiling.
Second‑year back Woody Marks will likely stay involved in passing situations, but he was mostly inefficient as a runner during his rookie season, finishing with 703 rushing yards on 3.6 yards per carry and 208 receiving yards.
That leaves early-down and short-yardage opportunities available for Montgomery to claim. If he secures those snaps as expected, he becomes one of the strongest RB3 candidates with true RB1 potential.
Bhayshul Tuten (RB- JAX)
Bhayshul Tuten also enters 2026 as a compelling RB3 with real RB1 upside after Travis Etienne Jr.’s move to the New Orleans Saints opened a major opportunity in the Jacksonville Jaguars backfield.
Tuten flashed burst and versatility in limited work last season, and his skill set fits the offense that Liam Coen runs.
Jacksonville had the chance to chase bigger names in free agency, but the team made only one meaningful addition in Chris Rodriguez Jr. Rodriguez reunites with Coen from their Kentucky days, yet he still profiles more as a complementary piece than a threat to Tuten’s workload.
With the Jaguars passing on more proven options, Tuten has a clear path to early down work and a steady share of touches. If he adds even modest receiving production, he has the explosiveness and opportunity to climb from RB27 into the RB1 conversation.
Kenneth Gainwell (RB – TB)
Kenneth Gainwell is a long-shot RB3, more accurately an RB4, but he still has a narrow path to RB1 production if everything falls into place with the Tampa Bay Buccaneers. He currently ranks as the RB38 in ECR, yet his 2025 season with the Pittsburgh Steelers showed what he can do when given steady work.
Gainwell delivered the most complete year of his career, showcasing improved vision, burst and reliability in scoring situations, traits that could translate well in a Tampa Bay offense seeking stability.
A major part of his upside hinges on whether Bucky Irving can return to dominance. Irving battled injuries early in 2025 and never regained his rookie‑year form once he returned, averaging just 3.4 yards per carry after posting 5.4 as a rookie.
Irving’s inconsistency left Tampa Bay’s run game sputtering, and while the team still believes in his long‑term talent, the door is open for someone to take on more work if Irving does not rebound quickly.
That is where Gainwell becomes interesting. He has the passing‑down skill set to stay on the field and a clearer path to touches than most backs ranked in his range.
If Irving struggles again and Tampa leans into Gainwell’s versatility, he has the opportunity‑driven upside to make a surprising climb from RB38 into the RB1 conversation.
