Fans were cautiously optimistic as the Carolina Panthers welcomed the Buffalo Bills to Bank of America Stadium in Week 8.
Dave Canales had led his team to three straight wins and four victories in the last five contests. This was the measuring stick he needed to find out how far his team had come and how much hard work was ahead before they could be classed as a legitimate playoff challenger.
Not having third-year quarterback Bryce Young was a blow. And this quickly became a gut-punching reality check for fans who were dreaming of playoff football this season.
The Panthers just weren't at the races. They started sluggishly and allowed Buffalo to dictate proceedings. The Bills' much-maligned defense looked refreshed and refocused after their bye week, making life extremely uncomfortable throughout. Carolina's hopes of winning evaporated long before halftime, and it turned into an epic blowout.
It was a dismal afternoon for everyone associated with the Panthers. At the same time, they are still 4-4 through eight weeks. They have some challenging games upcoming, so brushing this off as a single bad outing and moving on quickly is crucial.
Before then, here are two winners and five losers from Carolina's defeat to the Bills in Week 8.
Winners and losers from the Carolina Panthers' capitulation against the Bills
Loser No. 1
D.J. Wonnum - Carolina Panthers OLB
The Carolina Panthers are greatly missing the presence of free-agent signing Patrick Jones II. He's out for the season with a back injury, and general manager Dan Morgan has done nothing to fill the void yet, relying on those around him to step up their performance accordingly.
Nic Scourton has answered the call. His rookie classmate, Princely Umanmielen, is taking longer to adjust from college to the pros. And then, there is D.J. Wonnum, who is not doing enough to offset the loss of Jones.
Wonnum is the established veteran presence in Carolina's edge-rushing room. He's also in the final year of his deal, so his performances are being monitored closely by those in power before a decision on his future is due. That could legitimately go either way right now.
The former South Carolina prospect struggled to set the edge effectively on running plays. Buffalo recognized this almost immediately and took full advantage, blazing a trail with James Cook III to put the game out of sight almost before it began.
He wasn't the only defensive player who failed to meet expectations. However, the Panthers need more from Wonnum moving forward.
Loser No. 2
Tre'von Moehrig - Carolina Panthers S
The Carolina Panthers' primary objective in Week 8 was to contain the Buffalo Bills' rushing attack. It needed to be a collective effort, but the size of the task awaiting Ejiro Evero's defense couldn't be overstated.
This was a game where Tre'von Moehrig needed to show why the Panthers gave him such a hefty contract in free agency. The safety has impressed in recent weeks, especially closer to the line of scrimmage. But it didn't take long to realize that this wasn't going to be his day.
Moehrig wasn't the only one who struggled to keep up with the Bills' rushing attack. But when the running back did reach the second level, Carolina's free-agent signing didn't have the angles to make a significant impact.
The entire defense looked lost, but Moehrig is held to a higher standard. He's experienced enough to shake it off, but another stern challenge awaits when the Panthers travel to take on Josh Jacobs and the Green Bay Packers in Week 9.
Winner No. 1
Tetairoa McMillan - Carolina Panthers WR
Not many came out of the game with much credit. The Panthers needed everyone to perform at their peak to stand a chance of keeping up with the Bills. That didn't happen, and the inevitable collapse came quickly.
There were a few bright spots. Not for the first time this season, first-round wide receiver Tetairoa McMillan was one of them.
McMillan came as advertised. He was dynamic as a route-runner, displaying the required skills to gain just enough separation to make tough catches. The No. 8 overall selection in the 2025 NFL Draft looked like the only pass-catcher making explosive plays downfield, and things would have been even worse for Andy Dalton without him.
The former Arizona standout brought in seven receptions from 10 targets for 97 receiving yards. McMillan came close to finding the end zone but was halted near the goal line by Buffalo's stifling defense. Even so, this was another encouraging performance from the wideout amid the doom and gloom.
Loser No. 3
Carolina Panthers offensive line
The offensive line has once again proved its worth as a core part of Carolina's success. They've had to navigate some turbulence, but general manager Dan Morgan's successful mission to keep the group intact earlier this offseason had the desired effect.
There are now grave concerns. The protection in front of veteran quarterback Andy Dalton took some major hits against the Bills. They gave up seven sacks and conceded more pressures than arguably at any point during the 2025 campaign so far. If that wasn't bad enough, injuries completely decimated the unit at the worst possible time.
Stud right tackle Taylor Moton went out. Improving center Cade Mays was another. Their statuses moving forward are unclear, but it didn't take long for Dave Canales to confirm that versatile piece Brady Christensen had ruptured his Achilles tendon and is out for the season.
Fans will be hoping for good news on the other two, especially with the vaunted Green Bay Packers' defensive front up next.
Loser No. 4
Andy Dalton - Carolina Panthers QB
Bryce Young fought valiantly to prove his fitness after suffering a high ankle sprain against the New York Jets. The Carolina Panthers erred on the side of caution, giving veteran backup Andy Dalton the chance to start once again.
Dalton is experienced, but his best days are long gone. And his performance versus the Buffalo Bills became the driving force behind a dismal afternoon at the office for Carolina.
Everything that could go wrong did, for Dalton. He gave up an interception and two fumbles. He was under constant duress, looking hesitant and lacking conviction as he distributed the football. There were a couple of nice back-shoulder throws, but it was largely underwhelming.
It was almost cruel for Dave Canales to keep Dalton in the game at one point; that's how much he was struggling. The Panthers are hoping to have Young back at practice this week. The sooner he returns, the better.
Winner No. 2
Rico Dowdle - Carolina Panthers RB
As previously mentioned, there were very few positives for the Panthers to take from this blowout loss. They didn't look prepared, were sluggish out of the gate, and Carolina was always playing catch-up.
Rico Dowdle once again flashed when his number was called. The red-hot running back looked aggressive and explosive in equal measure. The problem was that Carolina didn't utilize his skill set as effectively as fans would have liked.
The Panthers are moving forward with a backfield committee, but it's evident who has the hot hand right now. Dave Canales is seeing things differently, giving Hubbard most of the work whilst Doowdle stood on the sidelines for almost the entire second half.
Considering the South Carolina product averaged 6.8 yards per carry compared to Hubbard's 2.8, that is simply inexcusable. Dowdle also didn't receive one target in the passing game, which is no doubt baffling for a player in such prolific form right now.
Loser No. 5
Carolina Panthers run defense
The Panthers' run defense has quietly become a strength this season. Fans were surprised by the steep upturn in production, especially considering this unit coughed up more than 3,000 rushing yards during the previous campaign.
Week 8 put this to the test. Josh Allen is among the league's most dangerous dual-threat quarterbacks. Running back James Cook III is dynamic, capable of turning the smallest seam into the most significant gain. He's a challenging proposition to stop once early momentum is generated, which is precisely what occurred at Bank of America Stadium.
Cook ran all over the Panthers. They failed to set the edge effectively, and the Georgia product took advantage at will. He broke off a 64-yard touchdown run in the first half to almost put the game out of sight. His 219 rushing yards from 19 carries could have been much worse had Buffalo not taken him out of the contest in the third quarter.
This was a step back for the Panthers' run defense after several positive steps forward. How they bounce back is crucial.
