You don't have the faintest idea what you are talking about. The officials are graded on every play in every game and evaluated at the end of the year. Some have been suspended for a number of games and the worst ones are terminated. The SEC doesn't give a list at the end of the year so we don't know who were . Most quitely go back to the Southern or OVC officiating.
One problem the SEC has is like the Chattanoogas, Citadel, and UABs of the world with coaches. If they have a really good official guess where he is going in a few years. Yep you guessed it, the NFL where the pay is a lot better and they have a pension. When I knew a bunch of officials in Atlanta in the 80s and 90s the SEC had no retirement plan, don't know if they do now or not but I am sure if they do it can't touch the NFL benefits.
As for throwing games it's almost impossible to do so these days with all the safeguards built in including background checks(NFL is like going to work for the CIA and SEC is almost as rigorous.) and video replays Also they are monitored for any suspicious big ticket purchases. If you are on the take put the cash in a hole in your backyard until 5 years after you retire.
PS- also difficult to throw a game because Vegas is constantly looking for suspicious bets with their ultra sophisticated computer systems.
I have gone to Vol games for 75 years and the only game I ever saw that I thought was thrown was the MCB against North Carolina by BIG officials.
