The Miami Dolphins head coach, Jeff Hafley has learned that even an NFL team's training camp can reveal valuable information to its opponents. Hafley discovered just how much information can leak after fans record practices and post footage online. The issue became particularly clear through a conversation with Kevin Patullo .
Patullo joined Miami this offseason as its passing-game coordinator after serving as the Philadelphia Eagles offensive coordinator in 2025. His experience provided Hafley with an unexpected look at how teams can exploit publicly available practice footage.

Hafley explained that Patullo t old him the Eagles had studied Green Bay's defensive pressure packages before the Packers faced Philadelphia. The head coach disclosed his new discovery during a recent appearance on the List – Dolphins Podcast.
"I didn't really think about it as much until we hired Kevin Patullo and he told me that before we played them in Brazil he had half my pressures on tape from training camp from people that videoed it and put it online."
The revelation was particularly concerning because Hafley had been Green Bay's defensive coordinator when the Packers faced Philadelphia in Week 1 of the 2024 season. Philadelphia defeated Green Bay 34-29 in São Paulo, Brazil. The Packers' defensive strategy apparently contained several pressure concepts that the Eagles had already seen on publicly available footage.
That creates a difficult problem for NFL teams. Training camp practices allow fans to get close to professional teams before the regular season begins. Those fans can record portions of practices and share them across social media within minutes.
For coaches, this can create an unwanted scouting resource for opposing teams. Defensive coordinators often spend significant time designing pressure packages that they hope will surprise quarterbacks and offensive coordinators. If opponents can identify those concepts before game day, part of that advantage disappears.
Hafley's experience shows how significant that information can become. The situation also highlights why NFL teams increasingly value joint practices. Unlike preseason games, joint practices can provide meaningful opportunities to test schemes against another team.
Teams want fans to attend practices and create excitement around the franchise. Those events help build connections with supporters while generating additional revenue. At the same time, coaches cannot afford to expose every important concept. That could force teams to become more selective about what they show during portions of practice that fans can record.
Hafley's experience with Green Bay provides a clear example of why that matters. The Dolphins now enter the 2026 season with Hafley as their head coach. He spent the previous two seasons as Green Bay's defensive coordinator before taking over the Dolphins. The lesson from his Packers experience could influence how he approaches training camp going forward.
The NFL is so competitive that small advantages can decide games. A disguised pressure, an unexpected coverage, or a new formation can create the difference between a successful play and a devastating mistake. If opposing teams can identify those concepts before kickoff, the element of surprise disappears.
