The FACT that he has not been offered much at all
It's curious to me that people on the outside have so much hubris that they come to an internet forum and make wild claims to
know what they cannot possibly know.
I'm not suggesting by that statement that I know something I cannot possibly know, either, btw. And I'm quite persuaded that Red hasn't made any team's short list for a HC hire. I'm not saying that. But is it possible he's been considered for another OC opportunity? Sure it is. Possible. Who knows. Not me. Not anyone else. But it's plausible.
Even for those who consider his coaching history to be trash (... I don't, but you're welcome to your opinion of course, free country...) you'll have to acknowledge the maxim that it's sometimes who you know, and JG certainly has a lot of relationships around the league given his career. A
lot.
The path worked for Gruden in relatively recent memory. And Cowher certainly has been coveted by some teams over the years, though it would appear he never pursued anything seriously. It's less plausible for Garrett, of course, because he doesn't bring the same Super Bowl ring cache'. But again... plausible? He's relatively young, and if we assume his regard grows as a TV analyst (which isn't a given), in that case, yes, I think that's plausible.
