this may be a moot point because they are all probably gone at the end of the season anyway but...
Cam. Is. Not. The. Problem.
Get new staff and you'll all be making excuses to why you said he sucks.
I don't think Coaching staff is the Issue, we have the best DC of the last 10 years in the NFL as our HC, and Chud's running of the offense while has a few fans screaming he sucks has done a decent enough Job.
Ron Rivera didn't become the Panthers HC and suddenly forget how to Coach Defense, if he stays it will get better. there is just talent(Oline/WR/DB) gaps on offense and defense right now between where they are and where they need to be.
