What happened: The Buffalo Bills sent a Fourth of July greeting to Bills Mafia on Saturday, celebrating the holiday alongside America's 250th birthday. The NFL amplified the team's message as clubs across the league marked the milestone anniversary.

Why it matters: The semiquincentennial makes this a bigger occasion than a typical July 4, and teams are leaning into the moment during the quiet stretch of the offseason. For Buffalo, it is another touchpoint with a fan base the club has engaged all summer — a team entering the 2026 season viewed as the AFC's team to beat.

What to watch: Training camp is the next milestone on Buffalo's calendar as preparation for the 2026 season ramps up later this summer.
