I agree with this, kind of.
When something doesn't work you can't be pigheaded enough not to change it. He ****** around with STs for years and that probably cost us at least 5 wins over that span. The offensive design has been a joke his entire tenure, which is either his fault directly or his fault by who he's hired.
Was Campbell good for this program? Yes. Is he the best guy going forward? That's debatable. I see a guy who refuses to revamp the offense, negates special teams, and has often been owned in game management.
Do I want him gone. Not necessarily. But I'm not completely sold either.
