Expectations were SEC champion, making the playoff, maybe winning the whole thing.
All of it is still in play.
FSU was ranked 15th in the F+ update through week 0. Losing to a team ranked in the mid teens in week 1 when you still have all of your elite in-conference matchups left on the schedule is not a season-ender.
I've seen Kelly lose to good teams early on in the season at ND, and then go on to reel off a lot of convincing wins along with the team he lost to.
Point being, there's a lot of season left, and there's way too many people coming to way too many conclusions based on 4 quarters in week 1.
