College Football Nerds did their preview and said that Texas and Georgia mirror each other. Texas with good defense and suspect offense and Georgia being the reverse. In the end they used common opponents and that clearly favored UGA, so both picked Georgia (which is the safe pick.)
However, one did point out that Texas has only played one home game against a P4 opponent this year and all the rest have been on the road or neutral. The lesson he took from it was that if Texas struggled with places like Starkville and Lexington at night then they should struggle even more in Athens. While I think that take has merit it also might be the wrong lesson, as also you could say that Texas has a lot of experience this season playing P4 road games against equally talented teams (Ohio State and Oklahoma) and at night (Kentucky and Miss State) and as a result may be more battle-hardened than everyone expects.
That said, I don't disagree with them both picking Georgia.
