The Rushing Efficiency Gap: Why Yards Per Carry Matters More Than Total Yards

Dylan Riley leads in rushing yards. Aiden Flora averages 7.56 yards per carry. Those are two different kinds of dominance. By CFB Savant · October 13, 2026 · Numbers as of the Oct 13, 2026 snapshot.

Dylan Riley leads all non-quarterback rushers with 835 rushing yards. Jamal Roberts is second with 828. Cam Cook is third with 793. If you rank rushers by total yards, that is the order.

If you rank them by yards per carry, the order changes completely. Aiden Flora, who is fifth in total yards at 680, averages 7.56 yards per carry — the highest among the yardage leaders by a wide margin. Riley averages 6.57. Nate Sheppard, fourth in yards at 743, averages 6.30. Roberts averages 5.63. Cook averages 5.18. The median qualified rusher averages 4.98 yards per carry and 50.7 yards per game. Every one of these leaders is above the median, but they are not above it in the same way.

Volume vs. efficiency

Total yards reward workload. Yards per carry rewards efficiency. Yards per game blends the two: it rewards a back who gets a lot of carries and gains a lot per carry.

Riley is the volume-plus-efficiency leader. He has 127 carries for 835 yards, 6 touchdowns, and 139.2 yards per game. He is not just getting a lot of carries. He is gaining a lot on each one. Roberts is the volume leader with slightly lower efficiency: 828 yards on more carries, at 5.63 per carry, with 8 touchdowns and 138.0 yards per game. Cook is the pure workload case: 793 yards, 7 touchdowns, 132.2 yards per game, but at 5.18 per carry, the lowest among the top five. He is getting the ball a lot and producing, but each carry is worth less than Riley’s or Flora’s.

Flora is the efficiency case. He has 680 yards on far fewer carries, at 7.56 per carry, with 6 touchdowns and 113.3 yards per game. His yards-per-game number is lower than Riley’s or Roberts’, because he is getting fewer carries. But his per-carry number is the highest. If Flora got Riley’s workload at his current efficiency, he would be lapping the field. If he got it and his efficiency fell — which is what usually happens when workload rises — he would look more like the other leaders.

Sheppard is the balanced case

Nate Sheppard deserves a closer look because he is the best blend of the two. He has 743 yards, 8 touchdowns, 6.30 yards per carry, and 148.6 yards per game — the highest yards-per-game number among the top group. He is not first in total yards because he has played fewer games or gotten fewer carries, but on a per-game basis, he is producing more than anyone else. His 6.30 YPC is well above the 4.98 median, and his 8 touchdowns show he is finishing drives, not just gaining yards between the 20s.

Sheppard’s profile is why yards per game matters. Total yards can mislead when teams have played different numbers of games. Yards per game corrects for that. A back with 700 yards in 5 games is outpacing one with 800 yards in 7 games, even though the second has more total yards.

What YPC does not capture

Yards per carry does not capture fumbles, pass protection, receiving, or short-yardage conversion. A back who averages 7.0 YPC but fumbles twice a game is not better than one who averages 5.0 YPC and never fumbles. A back who gains 6.0 YPC on 1st-and-10 but cannot convert 3rd-and-1 is less valuable than his YPC suggests. CFB Savant shows fumbles and longest run on the rushing card for exactly this reason: they add the context YPC leaves out.

YPC also does not adjust for opponent or game script. A back who runs against tired defenses in the fourth quarter of blowouts will have a higher YPC than one who runs against fresh, stacked boxes in close games. That does not make YPC useless. It makes it a starting point, not a final judgment.

What happens when workload grows

Efficiency usually falls when workload rises. A back who averages 7.56 YPC on 90 carries will rarely average 7.56 on 200 carries, because defenses adjust, because short-yardage carries drag the average down, and because the back gets tired. That is why Flora's number is exciting but fragile. If his carries double and his YPC falls to 6.0, he is still elite. If it falls to 4.8, he is just above the median. The next few games will tell which path he is on.

The reverse is also true. A back like Cook, who is already handling a heavy workload at 5.18 YPC, has less room to fall. His efficiency is already workload-adjusted. If his workload stays the same and his YPC ticks up to 5.8, his total yards will jump without any change in role. That is why yards per carry and yards per game together are more informative than either alone: one tells you how good each carry is, the other tells you how often the back gets to carry it.

How to read a rushing card

When you open a rushing card, read three numbers together: yards per carry (efficiency), yards per game (pace), and total yards (volume). If all three percentiles are high, the back is dominant. If yards percentile is high but YPC percentile is middling, the back is a workload back. If YPC percentile is high but yards and yards-per-game percentiles are lower, the back is efficient on limited volume — a breakout candidate if his workload grows, or a complementary back whose efficiency would fall if he became the lead back.

Right now, Riley is the dominant case, Flora is the efficiency case, and Sheppard is the per-game case. All three are worth watching, for different reasons. See the rushing glossary entries and the 2026 rushing leaderboard.
