I don't know. Looking at what we've got in Houston right now, I'd be interested if I were one of the handful of teams that have been on the coaching carousel for years now with nothing to show for it.
Granted, 1 good season does not an organization make, but looking at the Texans, I see a core that should help the team towards many good seasons to come. So if I'm Miami, Cleveland, Oakland, Carolina, Tampa Bay, Arizona, St Louis, & Buffalo.... if I've got nothing to show at the end of the season, Kubiak may look pretty tempting.
Of course, this is from my perspective. I have no idea what any of those teams are thinking. But asking me to prove there is interest would be like asking you to prove there isn't.
Dom Capers got a second chance. So did Chan Gailey & countless other HCs... many who shouldn't have.
