No one talks about it because they just look at the names (Kuechly, Davis, Norman, Short, etc. etc.) but this is the worst Panthers' defense since 2012.
They're good not great against the run, only really good against the pass if they can get a pass rush (today they can't), and give up A LOT of yards. Their only saving grace is that they force takeaways and they're still pretty good in the red zone.
But them not being able to get a pass rush will doom this season. Give them time and Wilson, Palmer, and Rodgers will pick this secondary apart, Norman included.
