Agree on Oklahoma, this is the first time that Lincoln Riley has break in an inexperienced QB. Second game of the year for them as well, so it'll all still be pretty new.
As for the other games, Bama is beatable, we we're very competitive against them last year at Bama. I don't really have faith in Mac Jones. Florida is here, but they're pretty tough. If Georgia was here I'd feel really good since they have a new QB and new offensive line.
Personally from easiest to hardest:
Oklahoma
Bama (probably a tie between them and Georgia)
Georgia
Florida
