Honestly sounds like BS to me. Genuine coaching candidates don't generally telegraph their interest in jobs like this publically. This sounds like crafty agents spreading info to improve the market for their clients. The Herman stuff sure sounds like his agent is just trying to start the bidding war for him. Maybe the Strong stuff is just his agent trying to put feelers out that he's willing to leave Texas, or that he has other options, since its no secret that its been a disaster down there.
Beyond Butch, Schiano, Chud, and Mario, I just don't trust any public "rumor" that some coach is interested. When that info leaks its usually because they are trying to leverage the situation for other benefits.
