Fantasy Football Efficiency Metrics: How to Use Efficiency Stats in Fantasy Football
Why efficiency metrics are the key to finding overvalued and undervalued players: raw stats tell you what happened. Efficiency metrics tell you how it happened and whether it is sustainable. A RB with 1,000 yards on 280 carries is averaging 3.6 yards per carry — below average for a featured back. A RB with 1,000 yards on 200 carries is averaging 5.0 yards per carry — elite efficiency. Both produced 1,000 yards, but the first is a grinder dependent on volume, while the second is an efficient runner who would produce more if given more carries. Efficiency metrics separate the talent from the opportunity.
Efficiency Metrics Quick Reference
| Efficiency metric | What it measures | Strong vs weak threshold | Fantasy application |
|---|---|---|---|
| Yards per carry (YPC) | RB rushing efficiency — average yards gained per rush attempt | 4.5+ = strong; 3.5–4.4 = average; under 3.5 = poor (before O-line adjustment) | High YPC + limited carries = buy-low target; low YPC + high carries = sell-high volume play |
| Yards per route run (YPRR) | WR receiving efficiency — yards earned per route run, regardless of targets | 2.0+ = elite; 1.4–1.9 = above average; under 1.2 = below average | WR with high YPRR but low target share is route running well — volume will follow |
| Yards per target (YPT) | Receiver efficiency — yards per individual target received | 9.0+ = strong; 7.0–8.9 = average; under 6.5 = poor | Low YPT + high targets = high volume but low efficiency; regression candidate |
| Points per opportunity (PPO) | How many fantasy points a player earns per rush, target, or combined touch | Varies by position and scoring; compare within the same position | Players with elite PPO and moderate opportunity will score more as opportunity increases |
| Snap percentage | What percentage of available snaps a player is on the field | 70%+ = featured role; 40–69% = rotational; under 40% = limited role | Snap percentage rising = role expanding; falling = role risk or competition |
| Target rate (targets per route run) | How often a receiver is targeted per route they run | 20%+ = high target rate; 14–19% = above average; under 10% = low rate | High target rate + efficient YPRR = elite receiver; high target rate + low YPRR = forced ball (sell-high) |
How to Apply Efficiency Metrics
Using efficiency metrics in draft evaluation. Pre-draft efficiency research: (1) identify RBs with above-average YPC (4.5+) who are being drafted below their production level because they had limited touches — the efficiency is there; the opportunity was not; (2) identify WRs with high YPRR (2.0+) who are undervalued at ADP because their target share was moderate — the route running quality is there; the volume will follow if the offense uses them correctly; (3) avoid WRs with below-average YPRR even if they had a high target total — they may be getting targets, but they are not converting them efficiently, which is a sell signal; (4) compare efficiency within the same team to identify who is the “true” most efficient receiver when target share does not match efficiency; and (5) use efficiency metrics as a buy-low identifier: high efficiency + moderate volume = the player is better than their current ADP; low efficiency + high volume = the player is worse.
Using efficiency metrics for in-season decisions. Weekly and trade applications: (1) a player with declining YPC or YPRR over 4+ consecutive weeks is showing a true efficiency decline — investigate the cause (scheme change, injury, regression); (2) a player with rising YPRR who is not yet highly targeted is likely to see target share increases — buy before the market adjusts; (3) in trade negotiations, lead with efficiency data to support your argument: “He’s averaging 2.1 YPRR — the 3rd-highest in the league — but only has 6 targets per game right now; his volume will correct upward” is a compelling trade case; and (4) use PPO to identify which team’s offensive efficiency best serves your interests — a team with elite offensive efficiency produces more per touch, making their skill position players more valuable even with the same or lower volume.
