NFL running backs play a position that most would consider a revolving door. Many of them have extremely short careers in comparison to players in other positions. Their peaks are usually brief, sometimes lasting just a few seasons. The physical nature of being a running back and the constant beating they receive are some of the factors why it often happens this way.While a running backs' production can fall off relatively quickly, they also have the ability to burst onto the scene and make a huge difference. Every NFL season features breakout running backs that elevate their play to new heights. Here are five who could potentially do so during the 2022 NFL season.#1 - J.K.
