The 73-year-old Carroll clearly took the Raiders head coaching job because of the "one-in-a-lifetime" opportunity to work with the seven-time Super Bowl champion.

Pete Carroll was introduced as the new coach of the Raiders. He said he's excited to work with new general manager John Spytek, who was also introduced Monday.

One of the biggest stories this offseason already has been the return of former Seattle Seahawks head coach to the NFL, Pete Carroll. Last week, Carroll was announced as the next head coach for the Las Vegas Raiders. The 73-year-old had been out of football for a year but now he is back and ready for perhaps his greatest challenge yet.
