-5, the destruction of the Buckeyes by Purdue and a close win over an ever more questionable Penn State makes them more of a paper tiger based on resume.
The loss to Purdue hurts, but I still think that they are a top 10 team. If they finish 12-1 (with a conference title) they could find their way into the playoff.
Buckeyes looked pretty bad in a blowout loss to Purdue. They've got some issues that need to be fixed. Still only have one loss though and they have a nice win over Penn State.
