The 2020 college football season has entered its home stretch, even out West, where the Pac-12's blink-and-you'll-miss-it regular season is halfway over. Which stories stood out to me in a wild Week 12? Let's dive right in.

What on earth is wrong with Ohio State's pass defense?

On Friday, I wrote about title contenders and the questions they still need to address to reach the promised land. I could come up with only one "if" for Ohio State, but it turned out to be pretty pertinent:

The Buckeyes are 91st in passing success rate allowed and are struggling to force obvious pass situations. Despite having a pair of dynamite corners in Shaun Wade and Sevyn Banks, new defensive coordinator Kerry Coombs has chosen to mostly play a pretty passive zone coverage. ... Is this the week Coombs gets more aggressive? Or is this going to be an actual problem the rest of the season?

We don't have full Saturday charting data yet, so I can't say with certainty how much zone or man coverage Ohio State played beyond the norm. But whatever the Buckeyes tried in Saturday's 42-35 win over Indiana, it didn't work.
