Zac Etheridge specifies in Safety Coaching.
If we brought in another DB Coach it would be for someone who specifies in CB's.
Rather than have 1 guy try to cover the entire Secondary, it’s easier to have 2 guys just run their rooms & correspond with the DC.
CB's & Safeties have different responsibilities & it’s a lot more difficult to teach both groups from a technical standpoint if you don't have the experience doing both.
It makes more sense to have 1 LB Coach & 1 DL Coach. You don't need a DT & DE Coach, they have same responsibilities & nearly the same assignments.
