Seattle Seahawks cornerback Richard Sherman believes that his side have the "best" secondary in the NFL.

Pete Carroll's side's defensive backs are known as the 'Legion of Boom' for their renowned physical play and are part of a defense that is currently ranked second in the league for fewest yards allowed.

"I think we're the best in the game," Sherman told reporters. "We've got the best free safety in the game, probably the best left corner, best right corner — we don't switch sides, so we can't be like other guys who switch sides and do all that.

"But we can be the best right corner, best left corner, best strong safety in the game."

Seattle moved to 6-1 in their season with a 34-22 victory over their NFC West rivals the Arizona Cardinals on Thursday.
