Yes, I've been a fan since the 70's with a household full of Cowboy fans, so I know a thing or two about the ups and downs of this organization. When Jerry hired Bill Parcells it was an admittance that unproven coaches didn't work, and after Wade Phillips, Jerry realized that the trend was to go with a young hot shot and unfortunately for us fans he picked Jason Garrett whom proved to far from a talent as a head coach. When Jerry's back is against the wall, and it is, he has proven to do exactly what you say he won't do and that is change things up. For Jerry to go with another unproven coach would be going against his very track record.
What Jerry's track record does suggest is he will circle back the wagon and try another college hot shot if you ask me! This is what his tendencies show at this point and I think you know that. To even try a throw out some clown reference like he will promote Kellen or hire some unknown is slightly above trolling ...
