Seto, the Seahawks’ defensive passing game coordinator, played linebacker at USC and worked as a Trojans graduate assistant, linebackers coach and secondary coach under Carroll before joining him in Seattle after the 2009 season.
“He’s got all the information,” Carroll said. “He knows everything we’ve ever done and how we’ve done it.
“He’s a tremendous resource for us to always stay in touch with the principles and the philosophy and all that…. He’s been a special confidant to me to maintain our language and our belief because he goes back the furthest with me.”
On Sunday, he will attempt to help neutralize the New England Patriots and quarterback Tom Brady.
“He’s been a very integral part of everything that we do,” Carroll said. “He has meetings with the team every day…. He’s a big factor for us. He’s a great football coach.”
