No, they didn't. If you go the page for each voter for the AP, they list their current top 25 and in the right column it shows what they were the previous week, but it's confusing in that the ranking listed for the previous week is the overall AP ranking, not the individual voter's. Therefore, SBP saw that we were listed as #16 last week and (reasonably) thought that this meant that select voters had lowered us in their rankings after beating UGA.
In reality, a few voters just didn't have much respect for us before beating UGA...and appear to have only marginally more respect for us after beating them.
