You can argue whatever you want, but Torvik allows you to filter by date, and when you filter February 1st through March 28 (Iowa St. game - I left out UConn to make it a little more fair), Torvik has us as the #144 defense in the country. Significantly worse than the already bad #91 Torvik gives us for the entire season. Our win over Wisconsin in the BTT Championship game was our 2nd worst defensive performance of the season. Our worst was our win on 2/28 vs Minnesota (we always suck defensively against Minnesota lol). Every single game in the BTT was worse than our season average.
On the other hand, for that Feb. - just before UConn time frame, Torvik has us as the #1 offense in the nation. And then in that UConn game, we actually did play pretty good defense, but had our worst offensive performance of the season.
If anything, it looks like we played worse defense, but phenomenal offense, at the end of the season, and our E8 run was fueled entirely by offense. The run ended when our offense petered out.
