In the ever-evolving landscape of dynasty fantasy football, assessing player value is crucial, especially after significant offseason movements. Javonte Williams, Raheem Mostert, and Evan Engram have all switched teams, prompting a re-evaluation of their potential in the upcoming season.

Javonte Williams, now with the Dallas Cowboys, has shown signs of decline due to injuries that have hindered his performance, making him a candidate for a sell in dynasty leagues. Conversely, Raheem Mostert's age and potential replacement by rookie Ashton Jeanty at the Las Vegas Raiders further diminish his appeal, suggesting he should also be sold if possible. Meanwhile, Evan Engram's transition to the Broncos could lead to increased production due to the team’s need for reliable targets. However, sentiment leans towards holding or cautiously selling if the return is favorable.

The Las Vegas Raiders are gearing up for significant changes in their backfield leading into the 2025 NFL Draft. After a dismal performance last season, finishing last in the league with an average of just 79.8 rushing yards per game, they are actively seeking improvements. Alexander Mattison, who led the team with 420 rushing yards, has moved to the Miami Dolphins, leaving the Raiders to rely on Raheem Mostert, formerly of the Dolphins, who signed a one-year deal with Las Vegas. With Ameer Abdullah also departing, the Raiders are eyeing Boise State star Ashton Jeanty as a potential early-round pick in the draft. Raiders GM John Spytek was present at Jeanty's Pro Day, showcasing the team's interest in securing a running back who has proven to be a prolific scorer, tallying 29 touchdowns in his most recent season.

The Las Vegas Raiders have been strategic in their offseason spending with the second-most cap space in the NFL. They made headlines by extending Maxx Crosby, making him the highest-paid non-QB for a moment. However, the rest of their free-agent signings reflect a more conservative approach, with several players joining on modest contracts, emphasizing depth over splash signings.

Key additions include safety Jeremy Chinn, who signed a two-year deal worth $16.26 million with $12.25 million guaranteed, and offensive lineman Alex Cappa with a two-year, $11 million contract. Cornerback Eric Stokes and linebacker Elandon Roberts have also joined for one-year stints. The focus seems to be on building a competitive roster without overextending financially.

Free agency has significantly reshaped the fantasy football landscape this offseason, particularly in the running back position. A wave of signed veterans alongside a promising rookie class is set to challenge previous records. Najee Harris transitions to the Los Angeles Chargers, where he is expected to be a workhorse, showcasing his consistent rushing ability. Meanwhile, Javonte Williams aims to revive his career with the Dallas Cowboys after a lackluster stint in Denver. Rico Dowdle's impressive performance has earned him a role with the Carolina Panthers, while Jordan Mason joins the Minnesota Vikings after a productive season with the San Francisco 49ers. These moves, among others, indicate an intriguing offseason filled with potential and competition for fantasy managers.
