I think the reality is that this year, the big ten had some tough matchups. Michigan vs Alabama is a tough one. OSU should've won but lost to an amazing team. Wisky kinda pissed the game away (but give credit to Oregon, they have an opportunistic defense and I love their QB).
Iowa, PSU, Minny all looked great.
Illinois is happy to be traveling this time of year. Indy. Same.
Overall, I honestly believe the BIG10 is trending up over time. The Big Ten West in particular is recruiting really well, and will do well in the coming years. Wisky, Iowa, Minny, for sure, but Illinois is improving, and Purdue's rough year (OMG they lost their four best players to injury) is unfortunately an aberration. The sand people might continue to improve but I hope not. t
