The main takeaway is that the ACC is wide-open. Yeah, week 1 and all that but the juggernaut in the room already has a conference L. FSU will either put them out to pasture for the season, or give them life.
Clemson (and LSU too) got in the red zone enough to win, but came away with nothing far too many times. I wouldn't expect that from them again this season, so they will play better, but it looks like a continuation of last season when they were daring us to make a game of things.
Their OL and DL were very lackluster, and I don't see how that gets fixed in-season.
