Training camps are currently underway across the NFL, generating significant excitement among fantasy managers as draft season approaches. These camps provide valuable insights into teams' strategies for the upcoming season. However, they also present a risk for overreactions, as fantasy managers can be quick to judge performances during practices and scrimmages. For instance, a third-string wide receiver making a spectacular catch may lead to undue hype, while a starting quarterback's interceptions may cause panic.

Despite the potential pitfalls of overreacting, training camps do offer vital information regarding unresolved position battles throughout the league. This includes situations like the quarterback competition in Indianapolis or the running back race in Dallas. As players strive for more prominent roles, recover from injuries, or seek to make an impact in their first season, opportunities for 'sleeper' candidates emerge. The term 'sleeper' may be overused, but it generally refers to players who are often available in the later rounds of drafts, possessing the potential to significantly outperform their draft cost. Each player discussed in this article is typically available in the double-digit rounds and could emerge as the type of late-round draft pick that contributes to fantasy championships.

One such candidate is Sam Darnold, currently sporting an average draft position (ADP) of QB28 or 178th overall. Darnold experienced a remarkable year, leading the Minnesota Vikings to a 14-3 record, throwing for 4,319 yards, and finishing as the QB7 in fantasy points. But with the Vikings opting to acquire J.J. McCarthy, Darnold has moved to the Seattle Seahawks. Despite skepticism regarding whether his success can be replicated with a new team, some analysts believe Darnold’s new environment could be conducive to fantasy success. Seattle's offensive coordinator, Klint Kubiak, offers a system favorable for quarterbacks, although the team's offensive line has raised concerns. While there may be a drop-off in receiving talent compared to his prior team, the opportunity for Darnold to produce considerable fantasy value remains.

In a more dormant fantasy landscape, Indianapolis Colts quarterback Daniel Jones is poised for an overlooked opportunity with an ADP of QB32, 238th overall. As of now, Jones has not secured the starting role, and his past season for the New York Giants saw him struggle with just over 2,000 passing yards and eight touchdowns. However, with rookie Anthony Richardson sidelined, reports indicate that Jones has built a significant lead in the starting competition. Historically, Jones has demonstrated the capacity to be a relevant fantasy quarterback, with a notable performance in 2022 when he achieved over 3,200 yards and 15 touchdowns, complemented by substantial rushing statistics. Should Jones prevail in his competition, his advantages over Richardson and the improved weapons at his disposal could lead to greater productivity than his current draft status suggests.

Another player worth monitoring is Javonte Williams, with an ADP of RB38, 112th overall. After showcasing tremendous potential as a rookie, Williams faced a significant setback due to a knee injury. In 2024, his numbers dipped markedly, but reports indicate he now feels healthy and is ready to reclaim his role. Currently with the Dallas Cowboys, Williams faces competition from veteran Miles Sanders and rookie Jaydon Blue. If he can return to form, he offers a chance for the Cowboys to recapture strong fantasy output, especially given previous performances from Dallas's backs in recent seasons.

J.K. Dobbins, who has displayed solid numbers when healthy, finds himself in a similar situation. With an ADP of RB40, 119th overall, Dobbins has faced challenges with injuries throughout his career, yet his skills have kept him in the conversation as a viable fantasy option. Having recently signed with the Denver Broncos, Dobbins will need to compete against incoming talent but has the potential to carve out a significant role if he stays healthy and the coaching staff utilizes him effectively. Historical precedents show that a dual-back system can thrive, highlighting the opportunity for Dobbins to experience fantasy relevance.

Wide receiver Tre Harris, drafted by the Los Angeles Chargers, presents an intriguing case as well, with an ADP of WR54, 135th overall. Harris's impressive college performance translates into optimism for his NFL career, especially given recent changes in the Chargers’ receiving corps. Following the retirement of Mike Williams, Harris has a chance to emerge as the second option in a high-powered offense. Analysts have already begun to project his rise on fantasy boards, especially if the Chargers maintain their pass-heavy offensive strategy.

On the Cleveland Browns front, Cedric Tillman stands out as an under-the-radar option with an ADP of WR65, 169th overall. The uncertainty surrounding the Browns has led many fantasy managers to overlook their players, but Tillman's past flashes during a brief full-time role indicate his potential for a breakout year. If he can establish a solid rapport with the quarterback, Tillman might be in line for an uptick in targets, capitalizing on defenses focusing on his teammates. As the offseason progresses, Tillman's performance in training camp could influence his fantasy stock significantly.

Isaiah Likely is another player worth considering in the tight-end landscape, with an ADP of TE17, 145th overall. Likely's past performances suggest he has the potential to break out, especially if he can secure a more prominent role in the Baltimore Ravens' offense, which has created favorable outcomes for tight ends historically. If circumstances align — such as the performance and health of starting tight end Mark Andrews — Likely could provide value well beyond his draft position.

Lastly, Brenton Strange from the Jacksonville Jaguars, with an ADP of TE21, 177th overall, displays promising athletic attributes that could lead to a breakout. Strange's flashes of ability in his previous season combined with an improved offensive scheme lend credence to the belief that he may thrive as a key offensive contributor in 2025. Should he elevate his game and establish a connection with quarterback Trevor Lawrence, Strange could offer substantial value to fantasy managers looking to profit from a late-round tight end.
