John Chavis, who left LSU to become the new defensive coordinator at Texas A&M, had earlier sought a job on the South Carolina coaching staff as defensive coordinator, sources told the New Orleans Times-Picayune.
Chavis, who is from Dillon, was offered a three-year extension worth $1.33 million annually to stay at LSU.
He wound up receiving a three-year deal worth $1.67 million annually from the Aggies.
A source told the New Orleans paper that Chavis was upset with LSU's inconsistent offense, but that he had no hard feelings toward Tigers head coach Les Miles.
Miles hired Chavis in 2009 after Tennessee fired him and the rest of Phillip Fulmer's staff.
