Richard Sherman impressed by Seattle Seahawks additions

Seattle Seahawks cornerback Richard Sherman has revealed that he has been impressed by the additions his side have made to their secondary in the off-season.

The NFC West outfit bolstered the ranks of the 'Legion of Boom' by signing veteran Cary Williams and selecting Tye Smith in the fifth round of the 2015 Draft.

"I think he's doing a great job," Sherman told reporters on Williams. "He's been in the league for seven years now, and he's played the technique we play."

On Smith, he added: "I think Tye is going to be a good player. He's a little raw. Sometimes he gets, I don't want to say, but he just loses focus out there. Overall, I think he's playing good ball."

The Seahawks' defense was ranked first in the NFL in the 2014 season.
