The upcoming NFL free agency season is filled with potential game-changers, making it crucial for dynasty fantasy football managers to assess the implications of player movements. Running backs Najee Harris and Javonte Williams, both facing uncertain futures, stand out as buy candidates, given their previous production and the potential for new opportunities. Meanwhile, wide receivers Chris Godwin, Diontae Johnson, and Marquise Brown are also highlighted for their past performances, but injuries and team changes could impact their values significantly. Fantasy managers should consider acquiring these players before free agency begins to maximize their potential returns.

Najee Harris, entering free agency for the first time, has consistently delivered over 1,000 rushing yards in each of his first four seasons, positioning himself as a reliable RB2 option. He could thrive on a new team, particularly if he lands with a team like the Dallas Cowboys. Similarly, Javonte Williams' future in Denver appears bleak, but there remains hope he can regain his rookie form if he finds a better-suited landing spot.

Chris Godwin's 2024 season was cut short by injury, but he was on track for a top fantasy finish before that. His potential return to the Buccaneers could stabilize his value. Meanwhile, Diontae Johnson's availability might be enticing to managers willing to take a low-risk gamble, given his successful past despite a tumultuous year. Lastly, Marquise Brown's injury woes shouldn't overshadow his talent; he could be a surprise hit if he signs with a new team in need of receiving help.
