What happened: The Denver Broncos marked National Mascot Day with a social media tribute to their longtime mascot, Miles. The post celebrated the team's costumed sideline staple as a fan favorite around the league.

Why it matters: Mascots are a core part of NFL game-day culture and fan engagement, and Miles has been a fixture at Denver home games for years. With the team in the 2026 offseason, lighthearted content like this helps keep the fan base connected ahead of training camp.

What to watch: Expect more offseason fan-facing content from Denver as the club builds toward the 2026 season and the opening of training camp.
