NFL Preseason Week 1 Recap: Immediate fantasy football takeaways from Saturday's games

Key Points:

• Browns' backfield has condensed from a three-man to a two-man committee, with Quinshon Judkins handling 80% of snaps with starters and Dylan Sampson covering third downs; Judkins' increased role is promising post-injury, potentially making him a mid-range RB2 fantasy option.
• Browns' rookie wide receivers KC Concepcion and Denzel Boston have earned starting roles early, joining Jerry Jeudy in the rotation; Isaiah Bond appears as the top backup, while overall usage aligns with preseason expectations.
• Bears showcased multiple-tight end sets, even starting with four tight ends on the field, signaling a strategic shift that could influence Colston Loveland and Cole Kmet's roles, with rookie Sam Roush also seeing notable usage.
• Vikings used Tai Felton unexpectedly at X receiver over Jauan Jennings, with Jordan Addison spending more time in the slot; this unconventional alignment may impact fantasy outlooks and warrants monitoring.
• Giants' running back committee involved Cam Skattebo, Tyrone Tracy, and Devin Singletary rotating heavily, with no clear lead back emerging yet; wide receiver rotation remains unsettled amid injuries, with Malik Nabers as the only reliable fantasy option currently.
