I'm a cynic so I am going to say it. the playoff committee will select the teams using these two criteria:
1.) which programs will make us the most money?
2.) is there sufficient reason to include four of those programs without making it obvious that our main concern is number 1?
Then they'll pic the four teams that most satisfy 1 and 2.
So I do believe if we vastly improve, win out, and win by impressive margins, and other top teams go down with a loss, we may be included. Especially is Virginia Tech wins out--beating FSU for the ACC crown.
I don't think that will happen though; we are not a playoff team. VT isn't beating FSU. Though, stranger things have happened.
