As Week 4 of the NFL season approaches, fantasy football managers must utilize the waiver wire effectively, looking to bolster their rosters with promising free agents.

Sam Darnold has emerged as a quarterback to target, leading the Minnesota Vikings to a strong start. Bucky Irving's performance with the Tampa Bay Buccaneers makes him a valuable running back pickup. Jauan Jennings has gained attention as a wide receiver following a stellar game for the San Francisco 49ers. Darnell Mooney's connection with the Atlanta Falcons and Cole Kmet's resurgence with the Chicago Bears add further depth to this week's recommendations.
