Packers RFA Sean Richardson signs offer sheet with Raiders, per report

It's been mostly quiet in Green Bay since the Packers signed their biggest free agents to new contracts in March. Now, several weeks after most teams concluding their offseason spending, the Oakland Raiders have signed restricted free agent safety Sean Richardson to an offer sheet, per NFL Network's Ian Rapoport.

Rapoport's sources say the offer sheet is worth $2.55 million for one year. Green Bay now has five days to match the exact terms of the offer sheet or else they lose Richardson to Oakland. Because Richardson went undrafted in 2012, the Raiders would owe the Packers nothing if they chose not to match.

If Green Bay allows Richardson to depart, he would become the latest Packer to make his way out west to the Bay Area. Over the last few seasons, Raiders general manager Reggie McKenzie -- himself a former Packers front office executive -- signed Charles Woodson, James Jones, Brandian Ross and C.J. Wilson, all players who McKenzie helped bring to Green Bay. While Richardson signed with the Packers after McKenzie's departure, the safety was part of the final draft class scouted by the former director of football operations.

Richardson's departure would leave Morgan Burnett, Ha Ha Clinton-Dix, Chris Banjo and Micah Hyde as the only players on the Packers roster that have taken regular season snaps at safety.
