Paul - It was another generally embarrassing week across the Big Ten. But it is what is, and it’s ours, so...yeah...there you go.



Anyway, Sparty had a bye, and despite the loss at Oregon last week, they appear to be the best in the Big Ten by a fair margin. So they remain #1. Wiscy had a bye as well, but they haven’t been as convincing to me. DONU looked pretty good in Fresno, so I gave Nebraska gets the nod for #2 with Bucky #3. Because #homer.



And that’s where it gets complicated. From #4 to #10 I think you could throw darts and end up with something as correct as trying to slot teams against each other. This is the realm of "teams almost good enough to win" and "lost badly last week but rebounded against shitty teams this week". Notable in this group are THE Ohio State University who got trucked at home last week to a team that got beat at home by East Carolina and Michigan, who got shut out by a Domer squad that
