As NFL training camps commence, the excitement for fantasy managers intensifies with the impending draft season. This period provides valuable insights into teams' strategies for the upcoming season, while simultaneously presenting the potential for overreactions from fantasy participants. A third-string wide receiver making a noteworthy catch can lead to inflated expectations, while a starting quarterback throwing interceptions may provoke excessive criticism. Despite these tendencies, there is essential information to be gleaned from training camps, particularly regarding unresolved position battles.

Across the league, teams are grappling with key decisions, from quarterback competitions in Indianapolis to running back roles in Dallas. Players are not only striving for larger responsibilities but also aiming to recover from injuries or make impactful contributions in their rookie seasons. The term 'sleeper' is frequently used in fantasy discussions, typically referring to players available in later draft rounds who have the potential to deliver impressive performances. Each player highlighted in this analysis is currently being drafted in double-digit rounds on average and possesses the capability to evolve into a valuable asset for fantasy squads.

Sam Darnold, with an average draft position of QB28 and 178th overall, had a remarkable 2024 season, leading the Minnesota Vikings to a 14-3 record while throwing for 4,319 yards and 35 touchdowns, finishing as QB7 in fantasy scoring. However, after Minnesota opted for J.J. McCarthy as their future quarterback, Darnold moved to Seattle on a significant contract, prompting skepticism from the fantasy community about his ability to replicate his success with a new team. Yet, insights from Fantasy Alarm's Andrew Cooper suggest that Darnold's new situation may offer favorable conditions for success, notably within an offensive scheme designed by Klint Kubiak. Though concerns about Seattle's offensive line persist, the opportunity for a seasoned quarterback to thrive in a potentially advantageous environment cannot be overlooked.

Daniel Jones of the Indianapolis Colts, considered a low-risk option with an average draft position of QB32 and 238th overall, finds himself in a precarious position. His lack of consistent production, along with Anthony Richardson's emergence, has limited his appeal in drafts. Nevertheless, reports indicate that Jones has developed a significant lead in the competition for the starting role, particularly during Richardson's absence due to injury. Given his past performance, where he demonstrated the capability to be fantasy-relevant as a top-12 quarterback, if Jones secures the starting position, he could offer considerable value relative to his current draft cost.

Javonte Williams, with an average draft position of RB38 and 112th overall, once embodied boundless potential during his rookie season, showcasing impressive statistics before suffering a knee injury. As he embarks on his journey with the Dallas Cowboys, Williams reports feeling fully healthy for the first time since his rookie year. Despite competing for playing time against veteran Miles Sanders and rookie Jaydon Blue, Williams has the opportunity to reclaim a leading role, especially considering the troubles faced by both Sanders in recent seasons and Blue's physical limitations. Should Williams regain his previous form, he could emerge as a dominant force on the Cowboys' roster.

J.K. Dobbins, currently with an average draft position of RB40 and 119th overall, has shown promise when healthy, averaging 5.2 yards per carry and excelling during his time with the Los Angeles Chargers. However, Dobbins' injury history has created skepticism regarding his availability and role with the Denver Broncos, where the team's backfield situation has become more uncertain after drafting R.J. Harvey. Denver's head coach Sean Payton has historically relied on a two-back system, suggesting potential opportunities for Dobbins to thrive. If he performs well in training camp, Dobbins could exceed current expectations and become a valued contributor in fantasy leagues.

Tre Harris, a second-round pick by the Los Angeles Chargers, has piqued interest due to his impressive college performance at Ole Miss, where he averaged over 17 yards per reception. With Mike Williams' retirement creating a void on the roster, Harris has a chance to assume a significant role alongside Justin Herbert. Analysts like Derek Brown of Fantasy Pros have highlighted Harris's potential to ascend the Chargers' depth chart, especially if the team continues its pass-heavy approach. Should he excel during training camp, Harris might emerge as one of the top fantasy values this season.

In Cleveland, receiver Cedric Tillman has not garnered significant attention, yet his past performance indicates potential for growth within the offense. Averaging notable statistics over a brief period last season, Tillman's capability to secure a full-time role could position him as a key target in the passing game. If the Browns can stabilize their quarterback situation, Tillman may become a player to watch as he potentially capitalizes on favorable matchups against opposing defenses wary of Jerry Jeudy and David Njoku.

Isaiah Likely of the Baltimore Ravens, with an average draft position of TE17 and 145th overall, saw initial promise in the previous season but returned to a secondary position behind Mark Andrews. Despite this, he remains a player to consider when evaluating tight end options outside the elite tier. If Andrews were to miss time or perform below expectations, Likely could quickly ascend the rankings among tight ends. Training camp could provide insights into how the Ravens plan to utilize Likely, who possesses the potential to be a breakout star in the tight end landscape.

Finally, Brenton Strange of the Jacksonville Jaguars stands out as a potential sleeper option. Despite being a lesser-known name, his physical attributes and emerging role within the offense suggest the possibility of becoming a dynamic playmaker for the Jaguars. With a new coach favoring an offensive-minded approach, Strange could take advantage of defenses focused on other key targets. If he continues to develop chemistry with quarterback Trevor Lawrence, Strange may prove to be a valuable asset for fantasy managers, especially at a position often fraught with uncertainty.
