So far this year, average yards/carry:
Tyus 5.4 (long carry 46)
Hunt 3.9 (long carry 59)
Brune 4.1 (long carry 8)
McCormick 1.0
Where rushing is concerned, getting positive yardage every play is as important as long carries. If you had a running back who made 4 yards ever carry, never more, never less, the offense could never be stopped except by penalties. At the other extreme, making 31 yards on one play, then 1 yard a play for the next 9 plays also will average 4 yards a carry, but you will make only one first down.
If you exclude each running back's longest carry, you get:
Tyus 4.2 yards/carry on his other carries
Hunt 2.7 yards/carry on his other carries
Brune 3.7 yards/carry on his other carries
McCormick has only one carry
