Very little. It means very little at this point. Remember in 2014 when the first Playoff rankings came out? Mississippi State was #1, Florida State was #2, we were #3, and Ole Miss was #4. Only one of those teams made it in the end (FSU), and they got whipped by Oregon in the Rose Bowl.
Obviously, things can and will change between now and the end of the season. We’ve got a few weeks left to go, and the most pivotal games are still sitting on the table, ready to be examined after they’re played.
