The preseason has kicked off, providing valuable insights into the upcoming fantasy football season. However, it is essential to approach these early games with caution, as they only offer a glimpse into the bigger picture. By combining preseason play with other clues such as draft capital, mini-camp and training camp reports, and coaching interviews, analysts can gain a more comprehensive understanding of potential storylines.

One notable development from Week 1 of the preseason is Brian Thomas Jr.'s impressive performance with the Jacksonville Jaguars. Thomas played 100% of the snaps with the starters and showcased his skills with a 42-yard reception from Beathard on the third drive. With no clear alpha receiver on the Jaguars roster, Thomas has the potential to emerge as a standout rookie and become a valuable asset in fantasy football drafts.

In Buffalo, Keon Coleman demonstrated his potential by leading the Bills with a 100% route participation rate during his time with the starters. Coleman delivered a 27% target share and showcased his versatility by making an impact on both passing and running plays. While Mack Hollins, who did not play during this game, may take away some work, Coleman remains an intriguing prospect with high upside and unknown potential. He currently falls outside the top 100 picks on most sites, making him an appealing target for those looking for undervalued talent.

Caleb Williams displayed his skills with the Philadelphia Eagles during his brief appearance on the field. Completing four of seven passes for 95 yards and adding 13 rushing yards on a scramble, Williams showcased his ability to make clutch plays and convert third downs. Although it is crucial not to overreact to preseason performances, Williams demonstrated potential that could make him an exciting option for fantasy football owners looking for upside outside the top 12 quarterbacks in drafts.

Jayden Daniels had an impressive debut with the Chicago Bears, leading the team on an 11-snap drive and completing two of three passes for 45 yards, including a 42-yard dime. Daniels also showcased his rushing abilities with a touchdown from the three-yard line. Daniels remains a favorite target for fantasy drafts due to his potential and performance in Week 1.

Keenan Allen, playing alongside Caleb Williams, had 100% route participation and reps outside in 12 personnel. Allen played 47% of his routes from the slot, primarily during 11 personnel groupings. Allen's role and versatility in 2WR sets could significantly impact his fantasy value throughout the season.

DJ Moore showcased his connection with Jayden Daniels, posting a 63% route participation rate and leading the team with three targets. Moore's performance highlights his potential as one of the Bears' top wide receivers and his ability to make an impact on play action boots.

Rome Odunze had a 50% route participation rate and one target with the starters. However, if Allen continues to receive most of the looks in 2WR sets, Odunze's playing time and potential impact could be affected, especially early in the season. Despite this uncertainty, Odunze remains a talented prospect worth considering for fantasy drafts.

Cole Kmet and Gerald Everett both had 63% route participation rates with the starters. While Everett's presence may impact Kmet's fantasy value due to increased competition at tight end, Kmet remains a potential leader among these two players. However, his value may be diminished until later in drafts due to the arrival of Allen and Odunze.

Nico Collins and Stefon Diggs both had 100% route participation rates with Caleb Williams at quarterback. With Dell participating in 75% of the dropbacks on four Stroud dropbacks and leaving the field in 12 and 21 personnel groupings, it remains unclear how the Texans' wide receiver rotation will unfold this season.

In Las Vegas, Brock Bowers and Michael Mayer both had significant snap rates, showcasing their potential as top tight ends. With their impressive playing time and potential for increased targets once Kolton Miller and Jackson Powers-Johnson return from injury, Bowers and Mayer are worth considering for fantasy drafts.

Lastly, Pickens' impressive target share and performance with the Pittsburgh Steelers highlight his potential as a dominant wide receiver. With the Brandon Aiyuk trade rumors fading, Pickens emerges as an intriguing option for fantasy drafts, offering WR2 upside and potential value as a late-round pick.
