Regarding the Badgers, don't count them out. All the matters at the end of the game is that you can put a W in the column. Bielema's proven time and time again, except for one loss against Michigan last year, that they can do that. 17-1 under him.
But they haven't beaten anybody during this time, other than Arkansas in last years bowl game. Its a fact their non-conference schedule is the weakest of any highly ranked team. The Big 10 is overrated, although it might have more balance this year than it has been in the past. The Badgers have to play Ohio State & Michigan back to back and if they run the table and win both of these games, I'd say they would be worthy of a top 5 rating.
They do beat the teams they are supposed to beat and with the other top teams loosing they deserve to be moved up in the rankings, but if they loose they will probably drop a lot farther than other teams who lost their first game.
I don't dislike the Badgers, I'd cheer for them if they played ND or the Chicago Bears!
