Should we be #2? Based on what has transpired so far this year I would have to say yes.
Are we the 2nd best team right now? Impossible to judge based on such a wide variety of competition that all the teams have played. I've watched a lot of games over the past couple of weeks and we definitely deserve to be among the top 5 right now.
So much of these early rankings are all dependent upon your ranking before the season started. If you started in the top 10 and have two losses thus far then your ranking may seem to be overinflated if you are now in the top 10 or 15. If you were unranked to start the year and are perfect thus far then it is so difficult to crack that top 10 or 15.
Rankings in December are interesting and provide a good basis for discussion. Do they mean a lot right now? I think we each have to make our own conclusions on that. I give more credence to rankings starting in mid January after a few conference games are in the books.
Just my humble opinions.
