Look I am not being a homer when I say this, but let me make a few arguments here.
1. Bama will win the SEC again this year (pretty easy)
2. non of the current teams that are good, will dethrone Bama. (not Johnny football, not LSU)
You have to have programs that can rise up and beat them, that have in the past. To me there are only two choices. Florida is the closest option in my mind. However TN will be capable. TN is second all time in SEC titles and winning percentage in the SEC. They are the only program historically that has been able to dethrone Bama. In fact no team has ever beat Bama close to as many as TN did 7 years in a row. TN is capable of getting that back. This again is not a homer opinion, it is a fact. The great teams always rise up. Remember LSU is really not that great historically, even 15 years ago they were crap. Look at TN all time record against them.
Let me be clear, I am not talking about next year or even the next, I mean rising up and dethroning in a few years.
