It's not actually that uncommon. Once you have head coach money, you can bide your time waiting for the right job. A lot of coaches will end up taking a position coach role in the meantime; waiting for a HC or OC/DC type role the next season.
The bigger red flag is that no one wants him as an OC after a "year off" so to speak. Saban hired him as "Analyst" and Locksley just gave him a TE Coach position; which sounds like they are trying to put him in position where he can do the least damage coaching while still being able to recruit. Reaffirms the idea that recruiting is the only thing he's good at.
