Jeremy Pruitt heads to Tennessee, so Alabama needs a new defensive coordinator.
Here are five coaches who could see being considered for the job (listed in alphabetical order):
The native of Tallassee is in year 2 as a defensive backs coach of Crimson Tide after seasons in Central Florida, Tennessee and Kentucky.
Kentucky promoted Ansley to co-defensive coordinator in early 2016, but went to a lower position in Alabama, partly because he wanted to learn with Nick Saban and Pruitt, so he would be better prepared every time he had a opportunity for defensive coordinator.
In addition to being currently number 3 in the 247 ranking of composite recruiters for next year's class, Ansley is considered a promising man in the world of training who is known to be very thoughtful and a good type Xs and Os.
Saban is very familiar with Chavis, who has been a defensive coordinator of the SEC ator since 1995.
After more than a decade as defensive coordinator for Tennessee, Chavis was the coordinator defensive LSU from 2009 to 2014 and is now in his third season at Texas A & M.
However, the Aggies hired Jimbo Fisher and probably look to bring their own defensive coordinator.
Although A & M occupies just 59 th nationwide in total defense, the Aggies are among the first 25 in both sacks and tackles for a loss for the third consecutive year.
The former Auburn coach has been with the SEC Network since August after resigning as defensive coordinator for North Carolina in February in order to spend more time with his family, who still lives in Auburn.
Saban is said to have always had respect for Chizik, although it is not clear if Chizik even wants to retrain.
After qualifying 118 th nationally in total defense in 2014 under a different defensive coordinator, North Carolina improved to 79 th in 2015 under Chizik and then to 71 st in 2016.
The 36-year-old is a rising star in the training world and Alabama considers it extremely valuable, as evidenced by his salary of $ 950,000 .
Lupoi is widely considered the best recruiter in Alabama and one of the best recruiters in the country. He also helped with the development of players like Tim Williams and Ryan Anderson. But while some in the media present him as a natural candidate to replace Pruitt as Tide's defensive coordinator, at least some in the football world believe that Lupoi may need more time before he is ready to be a defensive coordinator, especially in a place like Alabama.
Born in Alabama and a former Crimson Tide player, Sherrer was an assistant to graduate from Alabama from 1998 to 2000 and then director of player development at Tide from 2010 to 2012.  Sports Illustrated and ESPN have mentioned Sherrer, who has been Georgia's outside lineback coach since 2014, as a possibility to replace Pruitt. However, there are many in the world of football who believe that Sherrer is more likely to end up in Tennessee with Pruitt.
Pruitt and Sherrer are good friends.
