Clemson's loss to Notre Dame should be interpreted more realistically. Notre Dame is actually a very good team when they play well; hence the preseason high ranking.
They just laid a few eggs but if they get their game on, they have the talent and showed a lot more discipline when they played us.
Down the stretch, if it weren't for those bad losses, they could be a team that would beat half or more top ten teams, albeit not GA and Ohio State.
Also, Clemson always has at least one bad game where they even almost lose to someone in a game Clemson should totally dominate, but they almost always win.
Lots of games left to play. If we got our act together and fielded an impressive defense, won out, yeah, we could be in the CFP, most likely to be stomped by GA. Same with Clemson.
