Understanding Rushing Success Rate: How Success Rate Measures Running Back Consistency
What rushing success rate tells you that yards per carry does not: yards per carry is the standard rushing efficiency stat, but it is badly distorted by a few long runs — a back can have a great yards-per-carry average on the strength of one 60-yard burst while being stuffed on most of his other carries. Success rate fixes this by measuring consistency: it counts how often a back’s carries are “successful,” meaning they gain enough yardage to keep the offense on schedule (a common standard is gaining a healthy share of the needed yardage on each down). A back with a high success rate is reliably moving the chains carry after carry, while one with a low success rate is boom-or-bust. For fantasy, success rate reveals a back’s down-to-down reliability and the quality of his rushing, which complements volume and helps you judge whether his production is sustainable.
Understanding Rushing Success Rate
What success rate captures:
The core of the metric: (1) it measures the share of carries that are “successful” — gaining enough yardage on a given down to keep the offense on track (roughly: a good chunk of the yards needed on first down, more on later downs), so it counts consistency rather than total yardage; (2) it rewards staying on schedule — a back who reliably gains positive, drive-sustaining yardage has a high success rate, which reflects steady, dependable rushing; (3) it is not distorted by long runs — unlike yards per carry, a single big run does not inflate success rate, so it better reflects what a back does on a typical carry; (4) it is a consistency signal, telling you how reliable a back is down to down rather than how explosive he is.
Why it differs from yards per carry:
The contrast: (1) yards per carry is skewed by outliers — a few long runs can make a boom-or-bust back look efficient, hiding that most of his carries gain little, which makes yards per carry a misleading standalone measure; (2) success rate isolates consistency — it answers “how often does this back gain useful yardage,” which is a different and often more reliable question than “what is his average”; (3) the two together tell the full story — a back with a high success rate AND a strong yards per carry is both consistent and explosive (ideal), while a high yards per carry with a low success rate signals a boom-or-bust back living on a few big runs; (4) success rate connects to the underlying skill and situation, complementing the talent and blocking signals from yards after contact and rushing yards over expected.
How to use rushing success rate:
Putting it to work: (1) use it to judge consistency and sustainability — a back with a strong success rate is reliably productive, which tends to be more sustainable than production built on a few long runs, so it supports a steadier fantasy floor; (2) flag boom-or-bust backs — a back with a low success rate but flashy yards per carry is volatile and a regression risk, so temper expectations and treat him as a lumpier play; (3) combine it with volume — success rate describes the quality of a back’s carries, but his fantasy value also needs the volume to matter, so pair it with opportunity share; (4) treat it as one input among several — success rate, yards after contact, and opportunity together give a fuller read on a back than any single stat, so use it to refine rather than drive your evaluation, the disciplined use of any metric in our advanced analytics toolkit.
