Okay, so I decided to dig a little deeper on offensive stats. It required a bit of manual work, so I only included playoff teams. Here are the offensive stats rankings for each team vs P4 bowl eligible teams(I added Boise St stats for Oregon since they are a playoff team), with those teams listed in parentheses:
