TL;dr version. Will probably be moot before the day is out.
I get the Marrone suggestion. CEO, older, stable, let the assistants do what they do, knows pro spread O's, and makes Phil feel like the Pillsbury Dough Boy. I get it. Will it shout, "Success!"? Nope. A more qualified and successful BOB is set to take the OC job at Bama if he doesn't get a HC gig in the NFL. So us taking a less successful fired NFL/Syracuse coach is meh to me. If that's what they choose to do, I will support it, because Lord knows we need to fire Jeremy and start over. But in 4 years I would expect to be back hear whining with the rest of you.
We all know that the upside is higher, quicker, with Freeze or Kiffin. Don't see UT agreeing to hire with their past baggage. Wish they would choose the path of the redemption story, but doubt they will. Herman is probably going to sit it out a year and may be a meh without some severe humbling. Napier is the prize, but with our admin he is probably going to wait on UF or LSU. Steele is hired. Like I have posted for days as well as others on here and TB/JA (the later I despise) indicates - that tells me they have the permission of their top HC choice(s). Steele is not the HC choice and no amount of back dooring by Phil and other supporters will make that happen IMO. Maybe an interim for a short period if they fire most of the existing staff - which is possible.
So that points back to Chadwell and Marrone. I get Hank and others wanting Marrone as discussed above. I would rather take a chance on Chadwell. Having studied everything I can watch on his O scheme now, I like what I see and I think it fits where the game is today. I think it is adaptable to the passing game and provides a balance that can go either way depending on roster talent and opponent. I think it brings excitement and youth to the game that is desperately needed at UT. We have become plodders and now, losers. I don't see this program doing anything new that they can excel at while having lesser talent for a long time to come. To me that speaks even more to the logic of Steele in the coaching room. After Mahlzahn's gimmicky mess of an O, he knows what will work and what will not with Chadwell's. The combo could be dynamic together if they are sold on each other.
