All the way? Not likely.
Like Jim said, a lot of talent this year, but young. Very promising for the next couple of seasons, but I fully expect a "let down" or "over-confidence" loss or two this season. Not to mention the difficulty of getting through the Big 10 unscathed. It's a TOUGH conference.
Also, we can't forget that the scandals are still fresh in a lot of pollsters' minds. They could run the table and still be ranked 3rd or 4th under 1 or even 2-loss teams.
