The better the defense, the better your team fares. One thing about this statistic is that it doesn't lie, and you can't argue with the fact that if you have a top notch defense, the more likely you are to be ranked.
For this argument, I pulled the total team defense rankings for teams whose defense was in the top 80. I stopped there because Nebraska's defense is ranked 66th in the country right now.
In any case, here's the results of my analysis:
1. If you are in the top 20 defensively, the more likely you are to be in the top 10. There are 15 teams with top 20 defenses that are currently ranked, 5 teams with defenses ranked 21-40, 4 teams with defenses ranked 41-60, and 1 team with a defense 61-80.
2. If you are in the top 20 defensively, the more likely you are to have at least 9 wins. Wins and losses begin plummet greatly based on your defensive ranking. The average wins/loss record in the top 20 defenses is 9-2. This goes down to around 7-3 for defenses ranked 21-40, 6-4 for defenses ranked 41-60, and 5-5 for defenses ranked 61-80.
Point being - being satisfied with at top 60 defense makes you average. Being satisfied with a top 30 -40 defense makes you just above average, respectable in some seasons. Being satisfied with a top 20 defense puts you in the hunt for conference and national championships.

One last thing - Notice that in the top 20 defenses, there isn't a single team that is below .500...
