several things ----------

Before the uniform number of conference games began in 1978, any team unbeaten in conference play won a share of the SEC title. In fact,you left LSU and Alabama off your list from 1961. LSU was 6-0 and Alabama was 7-0.

Through the 1968 season, the SEC assigned some out of conference games as 'SEC Games' to ensure every team played at least 6 SEC games.Hence, North Carolina vs Georgia in '66. (In fact,LSU only played 4 true SEC games in 1968 as games vs TCU and Tulane counted as SEC games).

For whatever reason, Alabama and Ole Miss had a two game series in 1980 and 1981 knowing full well they wouldn't count as SEC games and were considered 'non conference' games.

In 1976 Kentucky lost to Mississippi State.However, a year or so later the NCAA had Miss State forfeit several,if not all games in 1975 and 1976, including the '76 UK game. Kentucky was retroactively awarded a share of the 1976 SEC title with 5-1 Georgia.

I think somewhere in this thread it was mentioned (correctly) that originally in 1984 Florida was named SEC champion while not being allowed to go to the Sugar or any bowl. In the Spring of 1985 AD's and Chancellors/Presidents voted to strip Florida of their 1984 title and make them ineligible for the upcoming 1985 season title.
