SEC honks Please explain Ole Miss being ranked #11?

I admit that ranking UF in the Pre Season in the top 25 was a bit whacked but given UF's success in the SEC.( They are the most successful team in the SEC over the last 20+ years), I can understand the assertion that last years 4-8 season might be an anomaly.However, Ole Miss being ranked just out of the top 10 at 11.  Please explain who they have played that should be considered "a signature win" this season for a team that lost 5 games last year? Which of the 4 wins makes them special?
