Georgia and USC are not that different statistically in terms of passing offense. Obviously the big unknown is the new QB, but the USC WRs do not have MUCH better stats
Plus Georgia has played a gauntlet of a schedule compared to USC
I think the key difference is that when USC transitioned from Moss to Maiava, it drastically changed how the passing game went. Maiava and Carson Beck are actually pretty similar, as both are very feast or famine in terms of QB play. Both make great plays in the passing game, but both also make critical errors. We don't know if Stockton can replicate the "feast" part that Beck or Maiava provided, and if the SECCG was any indication, it's not looking likely.
And in terms of sheer talent, nobody on Georgia is on Ja'Kobi Lane or Makai Lemon's level. Arian Smith is the closest, but outside of Alabama, his best games are against the worst teams on Georgia's schedule, such as UMass and 2-10 Mississippi State.
And I question the term "gauntlet" being used to define Georgia's schedule.
Yeah, Texas is a tough out. No question about it. But who are the next best teams they played?
Ole Miss? They're 9-3, lost to an awful Kentucky team at home, and Georgia got blown out by them 28-10.
Alabama? They just got beat by Michigan and finished 9-4 with losses to 6-6 Oklahoma and Vandy. Georgia also lost to them. Made Milroe look like Steve Young out there, when Michigan made him look like my neighbor Steve (good squash player from what I've heard tho).
Tennessee? Pretty good squad, but at 10-3 and they just got absolutely railroaded by Ohio State. Also Nico shouldn't have even played in that game.
Clemson? Drunkenly stumbling into the CFP by winning a very soft ACC isn't exactly anything to write home about, especially seeing the ACC's performances in the playoff and bowl games. Louisville destroyed them in Death Valley, and they also lost to South Carolina.
Georgia Tech? 7-6 and needed patented refball to escape with a win, while ND dominated them.
USC played Notre Dame (12-1), Penn State (12-2), LSU (9-4), Michigan (8-5) and A&M (8-5). All of those teams, sans LSU, had some of the best defenses in CFB.
Compared to Georgia with Texas x2 (12-2), Tennessee (10-3), Clemson (10-4), Ole Miss (9-3), Alabama (9-4).
I don't want to devalue Georgia's road. It was certainly tough, especially having to go on the road three times against ranked teams. But I wouldn't consider it leaps and bounds ahead of what USC went up against. The reality is that Ole Miss, Alabama, Tennessee and Clemson weren't really as good as their record indicated, and 3/4 showed it in their playoff/bowl games.
