The National Football League's legal tampering window opened Monday, officially beginning the free agency period that allows teams to negotiate with players from other organizations.

The opening follows what has been described as an active week of trades and high-profile scheduled player releases across the league. Teams can now formally discuss contracts with free agents, though signings cannot be officially completed until the new league year begins.

Among the notable player movements, linebacker Nakobe Dean will not be returning to the Philadelphia Eagles after spending four seasons with the team. Dean served as a defensive leader during his tenure with the Eagles organization.

The free agency period represents a critical time for NFL franchises to reshape their rosters ahead of the upcoming season. Teams use this window to address roster needs, retain key players, and pursue talent that may help improve their competitive position.

Player movements during free agency often set the tone for team strategies heading into the NFL draft and the subsequent season preparation period.
