NFL running backs could break out despite current depth chart positions

Several running backs in the NFL are poised for breakout seasons despite currently being buried on their teams' depth charts. Nick Singleton of the Tennessee Titans is behind Tony Pollard and Tyjae Spears, but possesses the speed needed for a larger role. Kaleb Johnson of the Pittsburgh Steelers is competing for the No. 3 spot, while Seattle Seahawks' George Holani may benefit from opportunities due to injuries among teammates. The rising performances of these players this summer could significantly alter the configurations of their respective teams as the season approaches.
