Training camps are currently taking place throughout the NFL, generating excitement among fantasy managers as the draft season approaches. This period provides valuable insights into teams' strategies and player performances for the upcoming season. However, it also poses risks, as fantasy managers often have a tendency to overreact to developments in camp. A memorable catch by a third-string wide receiver can make him a perceived future star, while a starting quarterback's interception struggles can lead to drastic downgrades in his value.

Despite the potential for exaggerated reactions, training camp offers important revelations, including unresolved position battles, such as the quarterback contest in Indianapolis and the running back situation in Dallas. Players are competing for increased roles, returning from injuries, or making strides in their first year. Each of these scenarios presents opportunities for fantasy managers to identify potential 'sleepers'—players available late in drafts who have the potential to exceed their average draft cost. Each individual featured herein typically has an average draft position (ADP) situated within the double-digit rounds, showcasing the potential to be impactful late-round selections.

One player to consider is Sam Darnold, who has had a tumultuous year. After an impressive 2024 season leading the Minnesota Vikings to a 14-3 record with 4,319 passing yards and 35 touchdowns, Darnold finds himself in a new environment with the Seattle Seahawks. Despite skepticism within the fantasy community regarding whether Darnold can replicate his previous success, new offensive coordinator Klint Kubiak's system could favor his contributions. While the Seahawks' offensive line has been criticized, Darnold has the opportunity to prove himself once more.

Another name to keep an eye on is Daniel Jones of the Indianapolis Colts, who has struggled to gain traction in fantasy leagues this season. While Jones faces competition from Anthony Richardson, he reportedly holds a significant lead in the quarterback battle. Having shown fantasy viability in previous seasons, especially in 2022, he is a potential candidate to return value if he secures the starting position. The Colts' improved receiving corps may further enhance Jones's prospects.

Javonte Williams, formerly of the Denver Broncos, is now aiming for a revival in Dallas. After a promising rookie season in 2021, Williams has battled injuries, but he recently expressed feeling fully healthy. Competing against veteran Miles Sanders and rookie Jaydon Blue, he has the potential to seize the lead role in a Dallas backfield that produced solid numbers last season.

Another player making waves is J.K. Dobbins, who has displayed potential over his five seasons in the NFL. Recently signed by the Denver Broncos after previously spending time in free agency, Dobbins could benefit from a two-headed backfield approach under head coach Sean Payton. Opportunities may arise for Dobbins to garner significant touches if he can stay healthy and perform well in training camp.

Tre Harris, a second-round pick by the Los Angeles Chargers, offers considerable upside. After an impressive collegiate career, the unexpected retirement of Mike Williams has opened avenues for targets within the Chargers' offense. His speed and route-running ability could make him a crucial asset in the receiving corps.

Fantasy managers may find it challenging to generate enthusiasm for Cleveland Browns players this season, particularly Cedric Tillman. Despite modest production in his first two seasons, Tillman has demonstrated flashes of potential during a brief full-time role last year. Assuming he secures a starting position this year, he could exploit single coverage as defenses focus on other key players.

Finally, Isaiah Likely remains an intriguing option at tight end for the Baltimore Ravens. While he finished lower in fantasy rankings compared to teammate Mark Andrews last year, there are pathways for Likely to increase his role, especially if Andrews's performance declines as he approaches 30. With the right conditions, Likely could emerge as a breakout candidate, capitalizing on the opportunity to receive more targets.

While the tight end position in fantasy football poses unique challenges, Brenton Strange of the Jacksonville Jaguars is another player to watch. Although he has primarily operated as an understudy, Strange's skill set and potential for a significant role as defenses focus on other offensive threats suggest he could be a valuable asset in a fantasy lineup.
