Los Angeles: Seattle said Friday they had released cornerback Richard Sherman, a key figure in the “Legion of Boom” defense that helped the Seahawks to a Super Bowl title after the 2013 season. “Thank you for helping win championships, shape our culture and define success in Seattle,” the team said in a statement. “We love you and your unwavering competitiveness, confidence and fierce passion for football and life. For that, you will always be a Hawk!” Sherman, who turns 30 on march 30, had one season left on a four-year, $56 million contract extension he signed in 2014, after winning Super Bowl 48. Sherman has recorded an NFL leading 32 interceptions since entering the league in 2011 as a fifth-round draft pick.
