Richard Sherman is confident in the Seattle Seahawks' secondary despite a dip in success last season.

"We're hitting our prime, that's what I'd say," Sherman told KIRO-AM. "I think at the beginning with our infancy, when we started this thing, it was our second, third years in the league. Now we're (in our) sixth, seventh years in the league. We're much more veteran. We have a great understanding of what's being asked of us and how to approach the game."

Sherman has been joined by Earl Thomas and Kam Chancellor in the Legion of Boom's core since the beginning.
