Richard and Mitch preview Thursday night's matchup between two of Richard's former teams as the San Francisco 49ers travel to Seattle to take on the Seahawks. After, Richard brings on Hall of Fame WR Calvin Johnson (AKA Megatron) and the two NFL legends discuss Calvin's early retirement from the Detroit Lions, what the Lions can do to fix their rocky relationship, and how Calvin felt watching former Lions QB Matthew Stafford win the Super Bowl after getting traded from Detroit. Calvin also shares stories about facing Packers QB Aaron Rodgers, what made him choose Georgia Tech over Georgia, and why he almost grabbed his gun when he was about to hear he'd been voted into the Hall of Fame. #volume #herd #colincowherd
