Most of the 10th coaches being added have been on the Defensive side of the ball due to the fact most staffs have 5 & sometimes 6 coaches on the Offensive side already.
Oh St hired Alex Grinch a former DC at Wash St, Clemson hired Lemanski Hall a former NFL LB that was a Defensive analysts with them for 3 years & Bama hired a former DC from UTEP/Southern Miss.
The only offensive coach I've seen being rumored as a 10th coach is Helfrich to Texas, there could be more though because the rule starts 1/9 and a lot schools will be making hires this week.
One thing common across D1 is almost all programs are hiring coaches with legit experience on whichever side of the ball they'll being hired for. Which makes sense. These hires seem more so geared towards actually having assistants with coaching & not just glitzy crootin guys.
Richt could go in multiple directions with this his pick, I like the idea of adding DVD as quality control he did well at ASA JUCO & is a guy that could be a legit DB coach after a few years experience as a QC/analyst.
Imo we need another's pair of eyes up in the booth on Offense, but I doubt Richt hires another Offensive assistant. Really interested to see who he hires though, because this staff could use some valuable experience at that 10th spot.
