From what I've seen of him, Muschamp will open with a base defense and see how things go. As you say, if the Tide is ripping off 4-6 yards a pop, he'll adjust. He'll bring a safety up, which will put pressure on our other DB's to stay with your receivers without much help.
I'm pretty sure yall will start with 8 in the box just because that is what every team has done against us this year (sometimes even bringing 9 in). Even UF creeped their safeties close to the line leaving a lot of 1 v. 1 on the outside. I honestly don't know much about yall's secondary outside of the obvious (Earl Thomas is a stud). What are your honest assessments about how yall's secondary will do against our receivers in 1v1?
