Bryan Harsin was apt in his assessment of his Auburn program after its latest loss, a double-digit setback against an Arkansas program the Tigers had dominated for much of the last decade.

Auburn fell to Arkansas, 41-27, in a game that got away from Harsin’s team in the second half, sending fans to the exits in droves by the end of the third quarter and the Tigers to their fourth straight loss. It’s Auburn’s second four-game losing streak under Harsin, and it dropped the team two games below .500 on the year and to 1-4 in SEC play.

“We’re just not good enough,” Harsin said. “…We got to be better, and we need a lot more action then just hope and wanting to, and all that. You’ve got to work for it.”

There’s no shortage of work and improvement needed for Auburn after Saturday’s loss, even after an off week to refocus and self-assess. With that in mind, let’s hand out some position-by-position grades for the Tigers after their latest loss:

Quarterback: A

Kudos to Robby Ashford, who seemed to be the biggest benefactor of Auburn’s off week. The redshirt freshman quarterback took a step back to reflect during the week off, and he honed in on some areas that have caused him trouble during the first half of the season. The result was by far the most well-rounded performance of his young career. He completed 24-of-33 passes (73 percent) for 285 yards and a touchdown, adding another 87 yards on the ground while finishing as Auburn’s leading rusher. He was 6-of-9 for 80 yards on third downs, converting five of those for first downs. Most importantly, he took care of the ball and didn’t commit a turnover (or a near-turnover) against Arkansas.

Running backs: B

The numbers didn’t jump off the page, but Tank Bigsby was Auburn’s best weapon against Arkansas. He averaged 5.7 yards per carry, though he finished with just 11 runs for 63 yards, and he added a season- (and team-) high six receptions for 37 yards. His 41-yard touchdown run late in the second quarter sparked some life to an Auburn offense that couldn’t capitalize on some good early field position. Jarquez Hunter added 30 total yards on 10 offensive touches, between carries and catches, and he scored a garbage-time touchdown to close the final margin with four seconds to play.

Wide receivers: B-

For Ashford to have his best day passing the ball, it only makes sense that Auburn’s receivers stepped up to make some plays. The most impressive was freshman Camden Brown, who had four catches for 83 yards and a touchdown. Ja’Varrius Johnson, Shedrick Jackson and Koy Moore also made some key receptions, but Auburn’s offense needs to do better to sustain and finish drives if it wants to fully find its footing offensively.

Tight ends: C

John Samuel Shenker was the only tight end to get involved in the passing game, hauling in two catches for 25 yards. On the plus side, both receptions converted third downs. On the other hand, Auburn needs more from a position it considered a deep one that would be heavily involved in the offense entering the season.

Offensive line: C

On paper, this looked to be one of Auburn’s best offensive games: 468 yards of total offense (the most since Week 1 against Mercer) and 6.6 yards per play (second straight game hitting that mark or better), as well as a strong passing game from Ashford and some big plays from Bigsby. But Auburn’s offense lacked some consistency, with an inability to finish drives and too much boom-or-bust situations. While the offensive line got some good push at times, allowing the Tigers to run for 183 yards, the team averaged just 3 yards per carry without Bigsby’s touchdown and a 34-yard scramble by Ashford. Add in three sacks allowed, and it there was plenty for Auburn’s offensive line to improve upon.

Defensive line: D

Credit to Colby Wooden and Derick Hall, who continue to show up on a weekly basis, but Auburn’s defensive front needs more than just those two to deliver. Lack of depth is wearing on the unit, and it’s showing in the stat sheet. Auburn allowed 286 rushing yards and four touchdowns on the ground against Arkansas, which averaged 6 yards per carry; it was the third straight game an opponent has rushed for at least 200 yards on Auburn, as the defensive front is struggling to contain teams from getting to the second level in the run game.

Linebackers: D

Owen Pappoe led Auburn with eight tackles and had 1.5 sacks—including one on the first play of the game—but run fits remain a problem, as opponents have been able to pick up yardage in chunks running the ball against the Tigers. On Saturday, it was Arkansas’ turn, with Raheim Sanders leading the way with 171 yards on 16 carries.

Defensive backs: D

Though no fault of his own, Zion Puckett will likely find himself on Arkansas’ highlight reel the remainder of the season after taking a fierce stiff-arm from KJ Jefferson on the second of two rushing touchdowns from the Razorbacks quarterback. Not only did Jefferson impact the game with his legs (and that stiff-arm), he picked apart Auburn’s pass defense. He completed 16-of-24 passes for 234 yards and a touchdown, and his 9.75 yards per pass attempt were better than his average entering the game (9.1), which was already 12th-best nationally. Six of his completions went for 18 or more yards, and he was 4-of-5 passing for 60 yards on third downs.

Special teams: D

It was another rough game at home for Anders Carlson, who was 2-of-4 on field goal attempts, had a kick blocked and booted a kickoff out of bounds. Carlson missed a 46-yarder on his first attempt of the game before connecting on his second try from the same distance one drive later. He made a 24-yard chip shot but then had a 52-yarder blocked on the opening drive of the second half — part of a pivotal sequence during which the game got away from Auburn. Add in a miscue by Keionte Scott, who let a punt bounce and turn into a 78-yarder for Arkansas (though Auburn scored on its ensuing possession, which started at its own 7-yard line), and it was a tough day for specialists. Even Oscar Chapman, who had a pair of 50-yard punts (with a long of 55 yards) and pinned four of his five attempts inside the 20, had a misstep in the kicking game that resulted in a 24-yard punt late in the first half.

Coaching: F

Things haven’t gotten better for Auburn, and even when one phase of the game starts to find its footing, the Tigers can’t get alignment in other aspects. Even with the added preparation time, coming off the bye week, Auburn couldn’t lay that first stepstone on the path toward salvaging its season. You can find fault in plenty of areas, but it all ultimately falls to the feet of Harsin, who has not been able to show he has what it takes to successfully run a program like Auburn. The Tigers are now 9-12 during his tenure and just 3-10 in the last calendar year, including a 1-8 record in SEC play during that stretch. As he said after the game, the Tigers aren’t good enough right now. That’s on him and his staff, because they aren’t good enough at this juncture, either.
