The preseason is done, and fantasy managers are sprinting toward Week 1 with a flurry of roster unsettled notes. Jawan Jennings may open the 49ers’ season on IR, Iyuk could start on the pup list, and Deebo Samuel remains a fantasy focal point with McCaffrey and Brock Purdy drawing attention. Brian Robinson Jr. just joined San Francisco’s backfield, signaling added depth at a position that could reshape early-season splits. Devon Achan’s calf—plus Raheem Mostert’s steady workload—keeps the Miami backfield fluid, while Ollie Gordon and Jaylen Wright vie behind him. The Browns backfield remains a nightmare of timing and talent, with Dylan Samson, Quinshon Judkins, and Jerome Ford all in the mix. Keon Coleman’s breakout potential in Buffalo, Evan Engram’s ascent in Denver’s system, and the evolving receiving corps around Cortland Sutton, Marvin Mims, and Rashid Shaheed provide multiple late-round sparks for fantasy rosters. This week’s risers and followers emphasize risk, depth, and the never-ending hunt for Week 1 upside.
