With the calendar flipped to 2018 and college football with only one game left this season after tonight, lets' take an early look at Ole Miss' 2018 depth chart and see who's gone and what each position group looks like for the first year of the Matt Luke tenure without the interim tag.

In the need to replace section, we include returning starters or significant contributors. The confidence factor is on a scale of 10 and reflects how we feel about the Rebels next season at that respective position. Here's a look at the Ole Miss defense, where the Rebels lose their top two and four of their top seven tacklers from last season.

Returning Starters: Benito Jones, Josiah Coatney

Need to Replace: None

Overview: Last year was a bit of transition at the defensive tackle position, as Ole Miss had to replace DJ Jones and Issac Gross, but 2018 will see the Rebels return the entire depth chart except for Herbert Moore.

Benito Jones headlines as the group, as the former Rivals100 prospect from Waynesboro, Mississippi, is quick twitched and powerful in the middle of the defense line. His sophomore season was a bit uneven, but he played through a shoulder injury and had a scare after collision during a preseason practice. The potential is there for him to be an elite force for Ole Miss.

Josiah Coatney (65 tackles, 3.5 sacks), who has been a social media favorite for Ole Miss fans in recent weeks, redshirted in 2016 before showing nice potential in his first season in Oxford. Ross Donelly and Austrian Robinson need to provide rotational depth to the unit in 2018, and Garrald McDowell is a swing defensive lineman that could be in at multiple spots.

Sincere David redshirted this past season after transitioning from playing offensive guard in high school.

Confidence Factor: 6.5/10

Returning Starters: Victor Evans

Need to Replace: Breeland Speaks, Marquis Haynes

Overview: That "need to replace" line is probably jarring for Ole Miss fans, as the Rebels lost Marquis Haynes, the school record holder for career sacks, and Breeland Speaks, who gave up his final year of eligibility to pursue the NFL. Haynes had at least seven sacks in each of his four seasons and tied the season school record with 10 in 2015. Speaks had seven sacks as a junior and played at a high level once he moved outside during the season.

Ole Miss will get lengthy end Victor Evans back from injury, and it's an intriguing but unproven ground around him. Charles Wiley and Markel Winters were highly touted recruits who show the measureables necessary, and Qaadir Sheppard, a Syracuse transfer, was injured for a great deal of 2017, so he could be a spark next season.

Ryder Anderson played well in spurts as a true freshman and should see an extended amount of time as a sophomore. He'll add weight to his 6-foot-6 frame.

Confidence Factor: 5/10

Returning Starters: Brenden Williams (on the 4-3 depth chart)

Need to Replace: DeMarquis Gates, Tayler Polk

This has been a constant point of criticism for multiple seasons, and it's another spot where Ole Miss lost its two most productive players. DeMarquis Gates put up an incredibly solid season in his final year of eligibility and unjustly went under the radar considering what he meant to the Ole Miss defense. Also, the Rebels lose walk-on Tayler Polk, who played in every game and gave Ole Miss valuable snaps.

Ole Miss also loses Jarrion Street, who was Gates' backup at the end of the season. He transferred to UAB following the Egg Bowl.

The returners on the two deep are Donta Evans, Willie Hibbler, Brenden Williams and Detric Bing-Dukes. Hibbler has flashed some upside, and Ole Miss has gotten quality snaps from Bing-Dukes if he's not asked to do too much. Williams never transitioned well from junior college in 2017. Evans had 17 tackles in 11 games.

Ole Miss hopes a youth movement takes shape, as the 2017 signing class had multiple linebackers. The likeliest candidates to fill roles and provide functional depth are redshirt Josh Clarke and rising sophomore Mohamed Sanogo.

Confidence Factor: 5/10

Returning Starters: Myles Hartsfield, Ken Webster, Javien Hamilton

Need to Replace: None

Ole Miss gets its entire two-deep back from the end of the 2017 season at cornerback, a position group that has some versatility and is solid.

Myles Hartsfield and Ken Webster return to headline the unit, as Hartsfield played well in his first year of full-time duty, and Webster was one of the team's best stories, returning from that gruesome knee injury against Florida State to be effective a year later.

D.D. Bowie, one of the best athletes on the team, returns for his sophomore season, and Ole Miss got a lot out of junior college transfer Javien Hamilton, who could be poised for a big second season.

Jalen Julius transferred following the season, but he would have had a difficult time breaking into the rotation without mounting injuries.

Confidence Factor: 8/10

Returning Starters: Zedrick Woods, Jaylon Jones

Need to Replace: A.J. Moore, CJ Hampton

Zedrick Woods is the foundation of the group. He's been a contributor since stepping on campus and makes everything flow more effectively when he's in the game. Woods is arguably the most valuable player on the defense. The Rebels also return swing defensive back Jaylon Jones, who was excellent as a cover corner as a freshman but switched over to safety as a sophomore. CJ Moore is basically a starter, as well, and gives the Rebels more experience in the defensive backfield. He was fifth on the team in tackles last season.

Montrell Custis, CJ Miller and Cam Ordway will also compete for spots in the rotation. Miller has earned a lot of positive comments since arriving in Oxford, and there are some expectations on him to take a step.

Armani Linton also returns, and the Rebels redshirted AJ Harris last season.
