We could have afforded Ellis. Key, in my opinion, probably looked at Ellis's experience and also felt that style of offense didn't fit his vision of the team. Georgia Southern was 41st in OFEI this year. Barbay at App State was 36th. So, yeah, I kind of think it is you are just stuck on a style of offense you love. One year as an OC all by himself is all Ellis has. Key did his dilligence and obviously thought Ellis was not the OC brain behind WKU's offense. Maybe if Key could've lured someone like Garrett Riley, he might have switched offensive styles. But that is where the bucks were not there.
Let's see, you're trying to minimize Ellis's history as OC, but defend Barbay with a one year performance at App State? Yes, his OFEI of 36 this year was impressive, however, App State already had a decent to pretty good offense (OFEI: 2021 - #56, 2019 - #39, 2019 - #45) BEFORE Barbay went there, and the HFC Shawn Clark at App State was the Co-OC/Assist HC there before being promoted after Satterfield left. Barbay was an OC for only two seasons previously (2021 Central Michigan, 2018 Stephen F Austin) and they were not impressive stints. Ellis was not only a record setting OC (Co-OC) at Western Kentucky, his 2022 GSU offense actually made enormous improvement over what was previously at GSU (From OFEI of 118 to 41 from 2021 to 2022!!!). It doesn't take a genius to figure out that Ellis was mainly responsible for GSU's improvement. BTW, if you want to do a deeper dive of the WKU OC situation, Zach Kittley (who Key was rumored to have pushed for) was the other Co-OC at WKU with Ellis. Before Kittley arrived at Texas Tech, their OFEI was #25, this year with Kittley at the helm it was #45. So maybe Ellis is pretty darn good with or without a Co-OC, huh?
But let's back further up and do a better analysis of Barbay and Faulkner than your superficial one year "analysis". Note that previous years OFEIs may have been under a different regime...I wasn't going to spend time investigating further, but in an effort to give a deeper look at the offensive situations at the respective schools I went back 3 years before each coach's OC tenure.

I think Faulkner did well at MTSU relative to MTSU's previous offenses (pretty well comparatively), but his other stops at OC were not anything you would look twice at. Barbay's history at OC would make me think REALLY hard about hiring him at a P5 school. Is his 2022 OFEI of 36 at App State a product of what was already there, or was he truly the architect of change? I would like to see another year or two at the same level in order to risk hiring him. His OC background isn't extensive or productive enough to say he could replicate that 36 OFEI at GT.
Am I "stuck on a style of offense"? Yes, I'm stuck on GT getting an OC that has an effective offense regardless of scheme. My HFC top choices were Bill O'Brien, Jamey Chadwell, Mike Houston, Willie Fritz, Curt Cignetti, Jeff Lebby. None of them have similar offenses...but they all have effective offenses. At the end of the day I don't care how we get from Point A to Point B with the football, all I care about is getting from Point A to Point B.
