According to Kenpom.
I checked to see if any top 10 defenses have missed the tournament before and the answer is yes all the time.
I went back and looked at the last time a top 10 offence missed and it was 2011. Since that time there have been 9 top 10 defensive teams that did not make in. We are very good defensively, and no matter how bad our offence is, I think our defence will be good enough to at least have us in the conversation on SS.
