Bama is not the defensive team they were in past years. UGA wouldn't do much better of a job stopping Oregon than UT did. Bama IMO plays them closer than UGA simply because Saban would come up with a gameplan that would slow Oregon some. I think Oregon would beat UGA by a comfortable margin.
Not unless the receivers play better and more consistent. That all works hand in hand. Worley has made mistakes... but the receiver play has not been good either.
