Rushing Yards vs. Rushing Attempts: Which NFL Prop Is More Predictable?

Side by Side

Why Attempts Track Role and Game Script

Rushing attempts count carries, including quarterback scrambles and kneel-downs, whether they gain or lose yards. Sacks do not count. That's what makes a running back's attempt total mostly a role stat. It tracks how big a share of the backfield's carries a back gets, what the industry calls his carry share, and how the game script plays out. A team that's protecting a lead in the fourth quarter tends to run more to burn clock, which lifts attempts even when the yards per carry aren't great. A one-yard dive and a fifteen-yard burst each count as exactly one attempt, so the number doesn't care how far the ball's gone.

Why Rushing Yards Carry More Variance

Rushing yards are, in effect, attempts multiplied by yards per carry. The first factor's the same workload that drives the attempt total. The second's where the extra noise enters, yards per carry. A single explosive play such as a broken tackle or a missed angle can carry a big share of a game's total. A back can get his usual number of carries and still land well over or under his yardage line, and it's all down to whether the blocking sprung a couple of long runs or every carry got swallowed up short.

A Worked Example

Say Jonathan Taylor gets a similar number of carries in two different weeks. The numbers below aren't real, just made up to show the idea.

The carry count barely moves, up one from 18 to 19. The yardage nearly doubles, because Week 2's got one long touchdown run instead of Week 1's carries mostly getting stopped near the line. That's the split: attempts caught the workload, and rushing yards caught the explosiveness.

What to Check Before Researching Either

You're weighing the same opportunity-versus-efficiency split described above, just for a running back. Start with carry share: how many of the team's carries go to this back instead of a committee partner, and whether that share's trending up or down. A committee backfield or a change-of-pace back stealing passing-down work matters more for attempts than for yards. Then there's the goal-line role, since a short-yardage back can score touchdowns without piling up yardage. Then check the expected game script. A team that's favored to lead tends to protect it by running the ball late, while a team expected to trail leans on the pass and only racks up carries in garbage time once the outcome's decided.
