Mike Vrabel was an NFL defensive player and a good one. He played the edge, mainly as a down defensive end but also on his feet. It's a position he's well-familiar with and one that will have a significant impact on his 2025 New England Patriots team.
Edge players are depended upon to put pressure on opposing quarterbacks. It's their number one assignment on any NFL defense. If they do it well, the team's defense will likely be solid. If not, you'll have a long season.
The 2024 Patriots' edge position was in shambles after Matt Judon was traded, and the top remaining edge, Joshua Uche, was as well.
