They are good but the rest of that conference makes you want to jump off a cliff. Duke is also in the same postion with a rare off year for the ACC.
Ohio State, Michigan State, and Wisconsin are all legit. I even think Illinois is pretty good this year. Every conference has bottomfeeders. Look at the Big East. Heralded conference but even they have shitty DePaul. And the SEC has LSU who hasn't even won a conference game all year. The thing that kills the Big 10 historically is the out-of-conference record. However, the Big 10 gets a pass from me this year seeing as they won the ACC/Big Ten Challenge for the first time ever.
