Using historical metrics generate an opportunity index from 100 percent to 0 percent of the chances of all deeper running backs by team. Looking for later draft round running backs to target. Start at rounds 10 to 20 using current ffpc adps
Deeper/late-round RBs (roughly rounds 10–20+ in FFPC-style drafts, often overall ~100–200+) get targeted for handcuff upside, committee shares, or standalone flex value in the 5–7 RB builds common to these leagues.

I generated an Opportunity Index (100% = elite historical upside if the starter misses time or in a committee; 0% = minimal projected path to meaningful touches) using:
Current/post-draft depth charts and projected roles.
Historical metrics: Backup RBOS (opportunity share) when starters miss time (e.g., 40–70%+ of touches in many cases, with past examples like Jordan Mason, Blake Corum, etc., delivering RB1–2 weeks).
Injury history of lead backs, passing-game usage, and team scheme (e.g., committees vs. workhorse).
FFPC ADP context: These players are typically undrafted or very late, making them high-upside darts for your bench.
Top Late-Round RB Targets by Team (Opportunity Index)
Focus on RBs with ADP in the 10–20+ range or undrafted in many mocks.
High Opportunity (80–100%) – Strong handcuff or committee upside:
Blake Corum (LAR, behind Kyren Williams): ~90–95%. Clone-like style + historical efficiency; often delivers big weeks if Williams misses time. Late-round steal.
Kyle Monangai (CHI, behind D'Andre Swift): ~85–90%. Proven volume in limited action; strong receiving skills for flex appeal. ADP ~8th round but can slide.
RJ Harvey (DEN, behind J.K. Dobbins): ~80–85%. Dynamic receiver with explosive potential; poised for big role in injury scenarios.
TreVeyon Henderson (NE, behind Rhamondre Stevenson): ~80%. Big-play upside shown in limited 2025 reps.
Solid Opportunity (60–79%) – Reliable depth with path to starts:
Ray Davis (BUF, behind James Cook): ~70%. Proven backup with receiving work.
Jonathon Brooks (CAR, behind Chuba Hubbard): ~65–70%. Former high draft pick returning; good standalone value. ADP ~11th round.
Tyler Allgeier (ARI, behind Jeremiyah Love): ~65%. Veteran goal-line threat.
Justice Hill (BAL, behind Derrick Henry): ~60%. Pass-catching specialist in a high-scoring offense.
Rico Dowdle (PIT, in committee): ~65%. Recent producer with Mike McCarthy ties.
Moderate Opportunity (40–59%) – Dart throws or situational:
Dylan Sampson (CLE), Malik Davis (DAL), Jordan Mason (MIN, behind Aaron Jones), Kenneth Gainwell (TB), Emmett Johnson (KC, behind Kenneth Walker): 45–55%. Upside in committees or if injuries hit, but riskier paths.
Braelon Allen / Isaiah Davis (NYJ): ~50%. Depth behind Breece Hall but athletic upside.
Lower Opportunity (<40%) – Avoid or last resort:
Many 3rd/4th-string or aging vets in crowded rooms (e.g., Samaje Perine, some rookie darts with unclear roles). Historical data shows <20–30% touch shares often lead to low fantasy output unless massive injuries cluster.
Strategy for Rounds 10–20 in FFPC
Target 1–2 high-index handcuffs (e.g., Corum, Monangai, Harvey) alongside your 5–7 total RBs. These hedge your early RBs and exploit the double-flex/TE-premium format.
Prioritize teams with injury-prone or aging starters (Henry, Cook, Swift, etc.).
Historical win rates improve with 3–4 TEs + balanced RB depth that includes these types—many winners stash 1–2 late RBs with 60%+ indexes.
Mock on FFPC to see exact ADP flow; values shift fast post-draft.
This index is directional based on May 2026 data—monitor camp battles and injuries. These late RBs are where league-winning upside often hides in deep 20-man rosters. Good luck!
