In a lot of aspects this IS a coaching issue. GERG and RR are throwing way too many schemes at this defense. 3-3-5, 4-3, "4-4", 3-4 all with position switches by the week. It's sickening. I would prefer to run a base 4-3 with the simplicity of an 8th grade defense so they at least know where they need to be on most plays.
Again, to prevent negbang, I love Coach Rod. But GERG has proven basically nothing at the college level.
IIRC GERG was in charge of a talented defense basically keeping teams from catching up to the offense with the Broncos. That is his specialty...not being forced to run a scheme that puts the most players of our worst position group (secondary) on the field.
I'm no coach and GERG knows 1000x more than I ever will (I think), but this stuff is so irritating to watch.
Hoke was top notch at this aspect of his job.
