League sources say the Green Bay Packers are working on rebuilding that defensive backfield. ESPN’s Adam Schefter reports the Packers and the Oakland Raiders both have interest in Colts cornerback Rashaan Melvin. He’s coming off two solid seasons in Indianapolis after having some success with the Ravens and Patriots. ESPN also reports former Packers receiver Jordy Nelson could be moving from one great quarterback to another. He has meetings set with three teams, including the New Orleans Saints.
