Since 2012, the Buckeyes haven't lost more than one conference game, and they have won the conference championship three of the last five years, including the last two. They were ineligible to win the Conference Championship in 2012, lost in the Conference Championship game in 2013, and didn't go to the championship in 2014 and 2016, but, at 8-1 in conference, were tied for the top in the East with Michigan State and Penn State both years, losing on the head-to-head match-up.
The Badgers look good, definitely, but Ohio State has, too, and they have the recent history as the conference's best to back it up. And no team has remotely tested the Buckeyes so far in 2019.
Every week in the power rankings I say Ohio State is #1 until someone proves differently, and that's just as true now as it has ever been.
