Here's the Big 10 (little 11) breakdown...
Scout.com: 2008 Big Ten Team-by-Team Schedule Breakdown
Says Iowa has the easiest schedule, and the likely record is 7-5... I guess this site doesn't have a lot of faith in the talent or coaching or something, because to go to one of the easiest (on paper) schedules for a big conf team and only be expected to improve by one win is not saying a lot...
(Honestly - I have no idea, just find all of these early signs and breakdowns interesting for all teams:
ISU, Iowa, etc- it's like gut instinct. Come August, they'll probably change their theories, but your first instinct is more times right than wrong)
