The running back position has an interesting relationship with the NFL Scouting Combine. On one hand, the Combine struggles to test much of what makes running backs successful on game day.
It’s difficult to simulate the speed and chaos of real game situations on a practice field, and that’s where running backs really get to show off their vision, processing speed, and contact balance. However, it’s also difficult to avoid paying attention when runners have great workouts with strong measurables and performance in field drills.
Lousiville RB Isaac Guerendo doesn’t have much tape, with 132 of his 231 career carries coming last year — though he’s averaged at least 6 yards per carry in each of the last three years.
