Running backs often face enormous physical demands from repeated carries and collisions. Some remain productive for many seasons, while others see their performance decline relatively quickly. What makes the running back position so physically demanding, and how has that influenced the way NFL teams build their rosters?

Running backs often have shorter careers since they take a lot of physical punishment through repeated tackles and collisions. Injuries can add up, while speed and explosiveness may decline earlier than in some other positions. Teams also have plenty of incentive to rotate backs, which can reduce one player’s workload and value.

Running backs take a beating almost every play, squeezing through crowded gaps and absorbing hits from much bigger defenders. That wear adds up fast, so I understand why teams rotate backs instead of relying on one player for everything. Having a strong backup can protect the starter and keep the running game productive.
