Fantasy Football: Jaguars, Seahawks backfield battles, Jonathon Brooks' role among biggest RB questions for NFL training camps

Key Points:

• NFL training camps are opening this week, sparking key fantasy football running back competitions for the 2026 season, with some teams having clear starters and others facing uncertain backfield battles.
• Jacksonville's RB competition centers on Chris Rodriguez Jr., recovering from foot surgery, and Bhayshul Tuten, who impressed coaches last spring and is seen as a high-upside fantasy pick due to his explosiveness and touchdown potential.
• Seattle's backfield is wide open after losing Kenneth Walker III and with Zach Charbonnet sidelined by injury; rookie Jadarian Price is favored to lead, but a committee including George Holani and Emanuel Wilson is expected.
• Pittsburgh's RB situation is complex, with Jaylen Warren and newcomer Rico Dowdle competing for touches, likely resulting in a split backfield and capped fantasy ceilings for both as RB3/flex options.
• Washington's backfield features Jacory Croskey-Merritt, Rachaad White, and rookie Kaytron Allen in a competition with unclear outcomes, encouraging fantasy managers to consider stashing multiple backs late in drafts to capture the eventual lead.
