Looking at the schedules, Penn State and Purdue (or Penn State and Wisconsin) could go undefeated since they don’t play each other.
I would laugh, since I think their formula for choosing conference champions is “the team that didn’t win it last”, sending Purdue to a BCS game.
Yes, I know the season just started. :)
At this point in the year, I’m still going with the conventional wisdom that Penn St./Ohio St. in Happy Valley will decide the Big 10 title. I do agree with your earlier post that we could have as many as 3 unbeaten teams this season.
