It's certainly optimistic but I could see it if I'm wearing gold tinted goggles. I could see it playing out like this (This isn't a prediction just a possible scenario). Bold are the wins.

I think @FSU early is a big chance for being able to steal a big win. They lose a good bit and hopefully we can catch them before they have really had a chance to come together. Otherwise I think the combination of a 4 year starting PG, great overall team experience, and a recent history of strong defense sets us up pretty well to handle the current situation better than most I would guess.
Either way going 13-7 would certainly take breaks going our way. Team staying healthy, one of the bigs stepping up defensively, someone like Usher/Parham/Maxwell/Sturdivant/Moore stepping up to give us a third reliable scoring option on the perimeter. I don't think any of those things individually is all that unlikely. I think what is unlikely is most or all of them falling into place at once, but those types of seasons do happen.
