No one knows anything [at our level anyway] except one thing: Coach will be thinking of it solely in terms of how to construct a strategy of giving us the best chance to win.
Having said that, and producing my own BS with some sort of humility, I think that he has only two viable options:
1). Start Tommy [because he doesn't want to just toss Andrew out there cold, and because Tommy pre-snap manages better] with the plan to put Andrew in ASAP when the offensive coaches have had a chance to see pretty much what [FSU] the opponent is doing. This would allow Kelly to assess how much running power we have that game for instance.
2). Start Andrew right off. This is the intriguing option of course. It would say a heck of a lot more than just the act itself. It would say that Coach thinks that Andrew is not just talented but ready to game manage the playbook. AND it would say that in the spring, the entire drama would be Hendrix vs Golson. The only way that Tommy would still be a viable starting candidate in the spring under the Hendrix-starts-the-bowl-game scenario would be if Andrew completely messes up. If he does [start] and doesn't [completely mess up], then Tommy will be a perpetual back-up serviceable game manager for the rest of his career.
Maybe then he will begin to get more nice things said about him, and how he got our new era off the ground, so that Andrew and Everett could really fly with the recruits that the improvement got us.
