[City, State] – September 27, 2025 – With NFL Week 4 kicking off, fantasy football enthusiasts are poring over projections and expert advice to optimize their lineups. NFL.com’s senior fantasy analyst, Marcas Grant, has provided timely guidance by unveiling his list of "sleepers" – undervalued players with the potential for significant point production – a critical resource for the millions of fantasy managers making last-minute roster decisions.

Published on September 25th, Grant's insights are particularly focused on favorable matchups and situational opportunities that could propel lesser-known or underperforming players into must-start territory for the upcoming weekend. The analysis prominently features three players from the anticipated "Sunday Night Football" clash between the Green Bay Packers and the Dallas Cowboys, alongside several running backs identified as having high upside.

Identifying Key Opportunities for Week 4

The concept of a "fantasy sleeper" is central to competitive fantasy football, referring to players who are typically overlooked, under-rostered, or priced cheaply, but are expected to exceed their usual output due to specific game conditions. Grant's weekly column on NFL.com has become a staple for players seeking an edge, and this week's edition arrives at a crucial juncture as teams solidify their strategies for Week 4.

Among the most discussed picks are those stemming from the high-stakes Packers-Cowboys game. This primetime matchup is often a high-scoring affair, presenting ample opportunities for offensive players to rack up fantasy points. While specific names are not detailed in the initial summary, the focus on this particular game suggests potential beneficiaries could be complementary receivers, tight ends, or even a secondary running back who might see an increased workload or a favorable defensive matchup.

Running Backs with High Upside

Beyond the Packers-Cowboys showdown, Grant has singled out three running backs as having significant upside for Week 4. This category of player is particularly vital in fantasy football, as running backs often form the backbone of a successful team due to their consistent opportunity for carries and receptions. Factors contributing to an RB's "upside" can include:

• Injury to a starter: A backup stepping into a primary role.
• Favorable defensive matchup: Facing a team weak against the run.
• Increased target share: More involvement in the passing game.
• Goal-line opportunities: Higher chance of scoring touchdowns.

The inclusion of multiple running backs suggests a deeper dive into team dynamics and defensive vulnerabilities across the league. Fantasy managers often struggle with finding consistent production at the position, making these "sleeper" recommendations particularly valuable for those looking to bolster their lineups or stream a player for a single week.

The Impact on Fantasy Players and Beyond

The release of expert analysis like Grant's is more than just a guide for game day; it's a significant event in the fantasy football community. Millions of players globally participate in fantasy leagues, dedicating considerable time to research, roster management, and tracking player performance. These weekly "sleeper" articles directly influence waiver wire claims, trade discussions, and ultimately, the outcomes of fantasy matchups.

For casual football fans, such analyses also add another layer of engagement, drawing attention to players who might otherwise fly under the radar. It encourages a deeper understanding of team strategies, individual player roles, and the intricacies of NFL game planning. As the season progresses, successful sleeper picks can often be the difference between a winning record and falling out of playoff contention.
