It doesn't really matter anymore...
You don't think VT's offense has improved over the course of the season you never extensively watched VT play. Which is okay because not everyone can watch every team. Just know that we went from anemic in the first half of the season to, at the very least, productive towards the end. I never said VT's offense was prolific, just that it has improved vastly over the course of the season. The offensive line has gelled, the new two QB system is working well enough, and Brandon Ore has been much better and is finally healthy. Meanwhile LSU's defense has went from stellar, to... well... less than stellar. Make no mistake, teams don't lose in triple OT because they can't hit a 2 point conversion, they lose twice in triple OT because their defense can't do anything to stop the other offense in the red zone. It's that simple. Where has the tiger defense gone? Fortunately, I really think they won't need it against the Buckeyes. Unless they get in triple OT.
And as I said, logically you put LSU into the title game, and they've done that. I just made the case for VT disregarding the fact that VT lost to them in the beginning of the season. It's a tough case to make and that's why they were given absolutely no chance by any of the talking heads, but I think I made my case pretty well.
As for Kentucky and Arkansas being capable of winning the ACC. Maybe. I'm not going to argue that the ACC is as good as the SEC, but I do think VT is better than Arkansas and Kentucky and would beat them both on a neutral field.
