There's really no new solid information on the subject, nor is there likely to be until Will Muschamp returns from vacation. I don't know when exactly that is, but it seems "mid-week" is the answer out there on the internet. That could be tonight, tomorrow, or Thursday.
Regardless, I think Auburn wants something in place this week. Nor do I really think Muschamp will let it play out through bowl season as the South Carolina sites have claimed. I think Will Muschamp knows Gus is on a time line and will move on if he doesn't get what he wants, so he'll make some form of decision this week.
Or he may not. If Auburn really wants him that badly, maybe Gus is willing to wait as long as it takes. I don't think that will be the case, though. I think we'll have an answer to the "Muschamp to Auburn?" question by the end of the week. He either accepts the position or Gus moves on to Plan B by the end of the weekend.
This is purely conjecture and my opinion, but that's how I believe it will play out.
Personally, I still think he's going to accept the position here at Auburn.
