I am using the same argument against UGA that you are using against Tennessee. If UGA were to lose to LSU, they become a 1 loss team that did not win their conference championship. They are in the conference with a conference champ with 2 losses. And if there are 4 conference champs with 1 loss or less if the rules you are saying apply do apply, UGA should suffer the same fate as TN so top 4 are OSU/UM winner, TCU, Clemson/UNC winner, USC. All are conference champs with 1 loss or less - UGA is not.
UGA could suffer the same fate at TN and drop from 1 to #5, or possibly #6 behind LSU or worse # 7 with TN 5, LSU 6 and them at 7. There are not getting the benefit this year of playing the #3 ranked team.
