Grantham, who just finished his first season at U of L, said in a statement released by the school that he was staying put. He had been offered a two-year deal by the Raiders.
He had interviewed with the Raiders on Monday but was back on the road recruiting on Tuesday and met with at least three prospects - along with U of L head coach Bobby Petrino - on Wednesday during the day in Georgia.
"I'm grateful for the opportunity to have interviewed for the defensive coordinator position with the Oakland Raiders, but I'm committed to the University of Louisville," Grantham said in the release. "I said when I came to Louisville that I thought we could win a national championship, and we are building toward that goal with the success we had this season. Coach Petrino and Tom Jurich have given me a great opportunity and I'm grateful for their commitment. My family loves it in Louisville, and I think we are establishing something special here with head coach Bobby Petrino and our staff. Our main objective over the next week is to finish strong in recruiting and continue to bolster this signing class."
Grantham installed a 3-4 defense at U of L and it was a major hit with the Cardinals finishing 9-4 and sixth in the country in total defense at 308.5 yards a game. U of L had 26 interceptions, including an NCAA record 14 by Gerod Holliman.
U of L allowed 21.8 points a game.
"We're very pleased and happy that Todd is going to be staying at the University of Louisville," Petrino said in the statement. "He's done a fabulous job with our defense that ranked in the top 10. He's one of the finest assistant coaches in the country, and you expect excellent coaches like Todd to get opportunities in the NFL. I've always had respect for the job that Todd has done throughout his career, especially this past year at Louisville, and we're happy that he and his family will continue to be members of the Cardinals' family."
Grantham has been huge in U of L's recruiting success. He's been the lead recruiter on several current commitments, including G.G. Robinson, Chandler Jones and Jonathan Greenard. He's also helped lure transfers Josh Harvey-Clemons, Shaq Wiggins and Jaquay Williams, who will be eligible to play next season for the Cardinals.
