The Big10 lost out this year for the same reason that Penn State lost out to Ohio State last year.
That makes no sense. Penn state and Ohio state are in the big 10. And it was wrong of them to do that to Penn state last year. The committee screwed the big 10 last year and this year.
Oh wait you’re right. It is the same reason as last year. ESPN doesn’t want the best big 10 team in the playoff.
