So here we are: No. 15 Auburn at Ole Miss. It’s the only all-SEC West matchup this week, and it features two teams going in opposite directions. For the Tigers, it’s a chance to run their winning streak to five, which would match their run to kick off the 2014 season. For the Rebels, it’s an opportunity to get back to the .500 mark.

What should we expect? Settle in, let us put on the prognostication hat and make a few guesses about one of the biggest battles of the week.

1. Marquis Haynes will make the biggest impact on defense: Haynes was a disruptive force in the Rebels’ 27-19 victory last year, when he made a season-high 6 tackles. He’s been Ole Miss’ best defensive player, leading the Rebels with 5 sacks and 7 tackles for loss.

Auburn’s Carl Lawson, who’s had a fine season in his own right, has a chance to have a big night pursuing Chad Kelly, especially if the Rebels fall behind and have to throw the ball 50 times or more. But Tigers tackles Darius James and Robert Leff will have a difficult time keeping Haynes out of the backfield.

2. Ole Miss will finally trail at halftime for the first time this season: This isn’t really a stretch in light of the fact that Auburn is favored to win by more than a field goal, but the Rebels have been the opposite of Tennessee this season, spotting Florida State and Alabama three-touchdown leads before losing both games. That won’t be the case this time as Auburn will use the top rushing attack in the SEC to control the ball and take at least a one-score lead at the half.

3. Auburn will not run for 543 yards: That was the Tigers’ total when they routed Arkansas, 56-3, last week, an SEC record for a regular-season conference game. What’s scary about that performance is that Ole Miss is last in the SEC against the run, surrendering nearly 227 yards per game.

What’s also impressive about that outing for Auburn is that the Tigers racked up that yardage while Kerryon Johnson, its second-leading rusher, was nursing his ankle injury. Unfortunately for the Rebels, Johnson will definitely play Saturday night.

Plus, Ole Miss is coming off a 38-21 loss at LSU in which it allowed Leonard Fournette to run for a school-record 284 yards. We’re not expecting Kamryn Pettway, who rushed for a career-high 192 yards last week, to reach that total. Let’s just say the Rebels will have another difficult game.

Not to pile on Ole Miss, but Hugh Freeze’s squad has to worry about QB Sean White’s ability to run as well. White, one of seven Auburn players with at least 100 rushing yards this season, ran for a career-high 61 yards against the Razorbacks.

4. Chad Kelly will complete more passes than Auburn throws: Kelly is averaging 22 completions a game while White is throwing the ball 20 times a contest, so if both teams play like they have this season, chances are this will happen. It’s even more likely to occur if Auburn establishes its running game and dictates tempo.

Coincidentally, White is averaging only 14 completions. He reached his season-highs for completions (19) in Auburn’s 18-13 victory over LSU last month.

For what it’s worth, Kelly’s season-low for pass attempts is 24. He’s completed at least 18 passes in every game this season.

5. Akeem Judd will have his biggest game of the year: The Rebels’ leading rusher is going to have to give Ole Miss more than he has this season, otherwise Kelly might be running for his life. At the very least, it will keep his team from remaining one-dimensional on offense. It might also keep Auburn pass-rushers Carl Lawson and Montravius Adams away from Kelly.

The spread (4 points) between two teams with different season-ending goals almost seems a little low. The Tigers should win and cover.
