What was wrong with his coaching at Miss State?
Mississippi State (2017)
Grantham, a nominee for the Broyles Award as the top assistant coach in the country, made an immediate splash in his lone year as defensive coordinator in Starkville. In his fifth season as a defensive coordinator in the SEC, Grantham guided the best MSU defense in recent memory.

Louisville
Grantham’s squads at Louisville ranked in the top-20 nationally in either scoring or total defense in all three years he was there.
Grantham’s commitment to an aggressive and physical style was evident in Louisville’s run defense, which finished top-15 nationally in all three of his seasons. The Cardinals were 12th against the run in 2016 (115.2 ypg), 14th in 2015 (120.2 ypg) and No. 10 in 2014 (108.9 ypg). They notably held All-American and Doak Walker Award finalist Dalvin Cook to only 54 yards on the ground in a 63-20 victory over Florida State on Sept. 17, 2016. From 2012-16, Louisville ranked second nationally in yards per carry defense (3.3) behind only Alabama (2.6).
Georgia
The 2012 season saw the Bulldogs finish with a 12-2 record, which included a loss to Alabama, the eventual national champion, in the SEC Championship Game. Georgia, champions of the Capital One Bowl, ended the campaign 18th in the country in scoring defense (19.6 ppg), holding five opponents to 10 or fewer points, and eighth nationally in pass defense (175.6 ypg).
In his second season at Georgia in 2011, the defense showed a dramatic jump in the national statistics. The group finished the year fifth nationally in total defense (277.2 ypg; 11th versus rushing, 10th versus passing), third in third-down defense (28.9 percent), fifth in interceptions (20), and seventh in turnovers gained (32), which ranked first in the SEC.
