This game would still mean nothing if the playoffs weren't expanded.
Georgia is 9-2. They can lose to Tech, fall to 9-3, beat Texas in the conference championship and be an automatic qualifier for the expanded playoffs. Not only an automatic qualifier, but receive a first round bye.
Under the previous 4-team playoff, no 3-loss team ever stood a chance at making it, not even the SEC champion.
The game against Tech means nothing to Georgia in the big scheme of things and the explanded playoffs are the reason.
Also, under the previous 4-team playoff, Georgia would absolutely have to win against Tech and in the SEC championship against Texas to have a chance at making the playoffs. The Tech game would have still had meaning (a lot of it).
