Throughout the chaos for Oklahoma over the weekend, there's a reality facing this team.

They still have games to play this season, and this weekend will be one of the toughest tests of the season.

The Sooners head out to Oxford, Mississippi to take on No. 18 Ole Miss on Saturday. They'll do that with significant changes on the offensive staff — Seth Littrell is out, Joe Jon Finley has been elevated to interim play caller and analyst Kevin Johns is now co-offensive coordinator and quarterbacks coach. And to top it off, Saturday's 35-9 loss to South Carolina marked the program's second-worst home loss since 1997.

Hopefully, it's a spark for the Sooners against a formidable Ole Miss squad. The Rebels entered last weekend's bye week losing two of three games, and both losses were heartbreakers. They fell to Kentucky at home, 20-17, before losing at LSU in overtime. However, they notably beat South Carolina 27-3.

But this'll be just the second road game in SEC play for the Sooners, and they've opened the week as an 18-point underdog. Here's a glimpse at what the Sooners can expect:

Ole Miss' passing attack

— While the Rebels have run the ball around 53% of the time, the thing that makes this offense go is the passing attack.

Dart has been incredibly efficient this season, ranking eighth in completion percentage, third in passer rating and first in passing yards per attempt (11.09). But the numbers also show how explosiveness the Rebels have been through the air — they rank fifth in yards per completion (15.1), second in passing plays of 20 yards or more (41) and first in passing plays of 30 yard or more (23).

Unfortunately, that's where OU's defense has been vulnerable. They've given up 24 passing plays of 20 yards or more, which ranks 91st.

But one positive? The Rebels have struggled to protect Dart this season. They're 91st in sacks allowed this season (2.43), and they surrendered six sacks in their last outing against LSU. Meanwhile, the Sooners are fourth in sacks per game (3.6) and recorded six sacks against South Carolina. Getting pressure on Dart is going to be pivotal for the Sooners.

— Ole Miss' rushing defense

Opponents have had essentially zero room to run against the Rebels, and that isn't due to a lack of effort. The Rebels gave up just 93 rushing yards on 47 attempts against Kentucky, 151 yards on 43 attempts to South Carolina and 84 yards on 24 attempts to LSU. The Rebels rank first nationally in yards allowed per carry (2.1) and have only given up 2.9 YPC against SEC opponents.

That's gonna be tough sledding for an OU rushing attack that has been in shambles. The Sooners averaged 1.3 yards per carry against South Carolina and surrendered 13 tackles for loss. The only bright spot was Jovantae Barnes, who turned in 17 carries for 70 yards (4.1 YPC). But given the struggles on the offensive line, it's hard to envision the Sooners have too much success against the Rebels on the ground.

That puts pressure on OU's quarterback — Jackson Arnold? Michael Hawkins? — to make plays through the air, which is where Ole Miss has been vulnerable.
