I think it means that nobody has a good read on the game versus the spread, which is understandable. Oklahoma is good, but the wild card is Tennessee. No question the Vols are more talented, but that is balanced by the youth and inexperience on the roster. So, you don't know what you are going to get.
If I were forced to be this game, I would take Oklahoma against the spread (I am a UT alum) because youth tends to derail in the first big game. But, you never know. The kids could come out and be better than expected and plant their flag on Saturday night.
