As the 2025 fantasy football season approaches, analyzing backup running back situations is key. A look at the Kansas City Chiefs reveals a competitive backfield featuring Kareem Hunt, Elijah Mitchell, and rookie Brashard Smith, all vying for touches behind Isiah Pacheco. Despite Pacheco's previous success, his 2024 performance raises concerns about his hold on the RB1 role. Meanwhile, the Los Angeles Rams are expected to see Jarquez Hunter outshine Blake Corum after solid college stats suggest potential. The Colts' situation with Jonathan Taylor's injury history makes Khalil Herbert and DJ Giddens valuable assets. With these evolving dynamics, monitoring these battles closely can yield significant fantasy dividends.
