I wouldn't put too much stock in any of the names being mentioned until/unless we find out who made it to round 2 of the interviews.
Round 1 is a screening process. By all reports, they talked to 10-12 people, and of those, we've got 5 "confirmed" names. That doesn't tell us who did the best, just who the media found out went through the interview. Beeston specifically said they were going to cast a wide net to start, after all.
For this stage, they weren't going to turn down an application from the "retread" candidates, as they, by definition, have experience. That doesn't guarantee anything beyond that first interview, though. That's just doing due diligence as part of a "wide net" initial process.
The only source saying that anyone is some sort of favorite has been Steve Dangle, who claims to have heard it from some players. And I'm sitting here wondering how those players could possibly know what direction FSG is thinking of going. My guess is that some players speculated, and it was interpreted as insider knowledge.
In any case, I'd be highly surprised if FSG has made up their mind prior to completing round 2 of the interviews.
