As has been said many times this offseason, the Raiders have a lot of needs. Safety was one of them and so was slot/nickel corner. When the Raiders went after Lamarcus Joyner, they were looking to kill two birds with one stone.
Joyner was listed with the safeties as a free agent because that’s where he played last season as part of the Rams Super Bowl run. But safety doesn’t define him. He’s played all over the secondary. That’s what he likes. That’s what defines him as a player.
