The Big Ten has four top ten preseason ranked teams. That is pretty stout.
We also all understand that some teams will not be as good as expected and vice versa, and that means some conferences will be the same way.
Georgia is a slight dog at Notre Dame at the moment, but is ranked a fair bit ahead in the polls. I don't think HFA is that significant, so I wonder if that is the betting public more than a "real line". I don't think UGA loses to ND this year. That could be the homer in me.
Folks are always suspicious of the ACC. Either they have an overall bad year, or when they have a very good year, folks think "Well, it was a fluke." They put a lot of guys into the League. In the past, my read was their teams were soft in the lines. They'd play other ACC teams that were soft and not realize it. That could be changing. Clemson stood up to Alabama who few would consider soft, and seemed to handle Ohio State reasonably well.
Since claiming we'll know more in a few weeks is a cop out, I'll GUESS the B1G is the top dog at the moment. I suspect either LSU or Auburn might be pretty good, I don't know which. It looks like Florida or Georgia in the East, which probably means South Carolina wins the division.
