If he's getting paid that much it's inexcusable to have an offense outside the top 25. This offense is well outside the top 100.
He should admit he's in over his head. From what I read he turned down mentorship and Freeman had to go after a WR coach who also lacks proper experience to be in this role at ND. Rees refused the hiring of a much more experienced WR coach because he wanted more say in the offensive strategy.
Rees 100% owns this. From recruiting to offensive hiring. All the mistakes he has made in the last 3 seasons are forefront now. Kelly had a way of hiding the issues instead of working hard to improve them. Rees doesn't have the experience to hide the deficiencies inherit in this offense and he certainly doesn't have the experience to fix any of it.
