NFL training camps are in full swing, creating a buzz among fantasy managers eager for the upcoming draft season. This period offers insights into team strategies and potential player roles for the season ahead, though it can also lead to overreactions. The nature of fantasy football often encourages managers to quickly elevate or dismiss players based on camp performances. For instance, a third-string wide receiver making a sensational catch might suddenly be viewed as the next big star, while a starting quarterback throwing multiple interceptions could be written off completely. It's essential to approach training camp news with a critical eye, as valuable information regarding position battles, player health, and rookie performances can emerge, setting the stage for potential fantasy sleepers.

The term 'sleeper' is frequently used in fantasy discussions, referring to players available in the later rounds of drafts who have the potential to significantly outperform their average draft position (ADP). In 2025, several players merit attention based on their current situations and the potential for breakout seasons. Sam Darnold, for example, had a remarkable 2024 season with the Minnesota Vikings, leading the team to a 14-3 record and finishing as the QB7 in fantasy. However, his move to the Seattle Seahawks raises questions about his ability to replicate that success. Despite concerns about Seattle's offensive line and receiving corps in comparison to the Vikings, analysts suggest Darnold is stepping into a favorable situation under new offensive coordinator Klint Kubiak, making him a worthwhile late-round consideration.

In Indianapolis, the quarterback competition is heating up with Daniel Jones, who has yet to secure the starting role. Despite a rough 2024 season with the New York Giants, Jones has reportedly gained ground in the competition amid uncertainty surrounding Anthony Richardson's availability due to injury. Jones’ past performances indicate that he can be fantasy-relevant, especially if he can replicate his 2022 success, where he finished as a top-12 fantasy quarterback. Meanwhile, in Dallas, Javonte Williams aims to resurrect his career after struggling with injuries. His acknowledgment of feeling fully healthy again suggests potential, particularly in a backfield that includes a questionable Miles Sanders and rookie Jaydon Blue. If Williams can regain his form, he may emerge as a valuable asset in fantasy leagues.

J.K. Dobbins is another player to monitor, as he has shown flashes of brilliance throughout his career, albeit with injury challenges limiting his appearances. His recent signing with the Denver Broncos and the presence of head coach Sean Payton, known for utilizing running back committees effectively, could position Dobbins for increased playing time and production. On the wide receiver front, Tre Harris of the Los Angeles Chargers is an intriguing name to watch following Mike Williams' retirement. Harris displayed impressive statistics at Ole Miss and may quickly become a reliable option for quarterback Justin Herbert. His performance in training camp will be pivotal in establishing his role within the Chargers’ offense.

Cleveland Browns receiver Cedric Tillman has faced skepticism given the team's struggles and crowded quarterback situation, but his potential for a full-time role this season cannot be ignored. Analysis points to Tillman's explosive four-game stretch last year and the likelihood of favorable matchups if he takes on a starting role. Lastly, Isaiah Likely of the Baltimore Ravens holds promise as a tight end given the potential for increased opportunities with Mark Andrews. Whether he can capitalize on those chances in camp will be critical for his fantasy outlook.

Overall, training camps provide a wealth of information that can shape fantasy strategies. By carefully assessing players’ performances and team dynamics, managers can uncover late-round gems capable of contributing significantly to their rosters.
