Marvin Sanders

Nebraska under Frank Solich

Nebraska Head Football Coach Frank Solich brought Sanders back to Lincoln in 2003 amidst a staff shakeup following the Cornhuskers' first non-winning season since 1961. Sanders was now in charge of the defensive backs at Nebraska, where 47 takeaways on the season set a new school record, and the Nebraska Blackshirts set new school and league records with 32 interceptions, the nation's highest-ranked pass efficiency defense, and the nation's second-best scoring defense. Despite the turnaround, Solich was fired after finishing the regular season 9-3. Nebraska Defensive Coordinator Bo Pelini subsequently led the team to a 17-3 victory over Michigan State in the 2003 Alamo Bowl to finish the team's season at 10-3, but he and Sanders, along with nearly all of the remaining staff, were let go after Bill Callahan was appointed as Nebraska's 31st Head Football Coach.

North Carolina

Sanders was named as co-Defensive Coordinator and Defensive Backs Coach at the struggling North Carolina for 2004. After finishing just 2-10 in 2003 before his arrival, Sanders helped the Tar Heels improve to a 6-6 (5-3 ACC) record and posting the lowest yards allowed by a UNC defense in three years. Under Sanders direction, UNC improved over 60 spots nationally in total defense. UNC Head Football Coach John Bunting was fired halfway through the 2006 season, and replaced by Butch Davis for 2007. Davis did not retain Sanders in his new staff.

Nebraska under Bo Pelini

After a one-year absence from coaching, Sanders was again brought back to Nebraska following the firing of Bill Callahan after a four-year record of 27-22. Callahan's replacement was former Nebraska Defensive Coordinator Bo Pelini, who had also been let go along with most of Frank Solich's staff after 2003. Pelini installed Sanders as the Secondary Coach for the Cornhuskers as part of his effort to turn around a program that had struggled under Callahan. Nebraska's Blackshirts defense improved to rank as the second best in the Big 12 Conference in 2008 after languishing near the bottom of the pack nationally in the years prior. In 2009, two of Sanders' players were named to the All-Big 12 first team, and the Nebraska secondary was among the highest ranked in the nation with the highest-rated pass defense and highest-rated scoring defense, and among the top ten nationally in rushing defense, sacks, and total defense. The 2009 Nebraska secondary intercepted 18 times while only allowing seven touchdown passes all season.

Sanders resigned from Nebraska on February 3, 2011, citing personal and family reasons.^[1]

USC Trojans

After agreeing to be FAU's defensive coordinator under new head coach Carl Pelini (Bo's brother) on December 5, 2011, Sanders left to become the USC Trojans defensive backs coach on February 12, 2012 under head coach Lane Kiffin.^[2] USC had gone through the whole 2011 season without a defensive backs coach as former coach Willie Mack Garza left days before the season opened stemming from his connection to Willie Lyles while at Tennessee.^[3] Sanders was the first coach hired by Pelini, as the Owls defensive coordinator. As per USC policy being a private school, Sanders financial agreement was not released. Pelini praised Sanders when he announced the hiring, saying they shared the same philosophy and that he had been the only candidate for the job.^[2]

Sanders was relieved of his duties^[4] at USC after the school hired Clancy Pendergast to be their defensive coordinator.

Marvin Sanders was officially hired as the head coach of one of the top high school football programs in the state of California, Loyola High School of Los Angeles, on February 24, 2013. Sanders has been the head coach for a total of four seasons, earning a win-loss record of 20-22 and 1-1 in the CIF Division 1 playoffs.

Prior to the 2017 season, Loyola High School and the Los Angeles Times announced, Marvin Sanders would not return to lead the Cubs' football program as the head coach.
