It will also take a new DC as well. He really stinks. I think frost was amazing but the defensive coach is terrible. The yards allowed to crap AAC teams is unreal.
People will need to reset their expectations on what good defense is. An offense like Frost's puts a ton of pressure on a defense. They are on the field a TON. you need to look beyond the face value stats. That defense was good enough to go undefeated. My guess is (Like me) most Husker fans watched the last 2 UCF games and are drawing a superficial conclusion that the defense is terrible. I would say (like I had to) take a step back and look at the big picture. With this offense I don't care who you roll out there, yards/points will be allowed by the defense. The thing that helped paint the picture for me was looking at margin of victory.
UCF ranks 3rd with +22.8 in the country, behind only PSU and Bama. (that is not a mark of a terrible defense) To me this becomes very impressive when you consider how the MOV looks without the final 2 games. The UCF defense played very well for a group that had to defend 76 plays/gm
It gets even more impressive when you look at the staggering improvement made in a very short time. 2015 MOV -25.8, 2016 MOV +0.4, 2017 MOV +22.8. (that seems to me to be a sign of incredible coaching, and playing complementary football)
UCF also boasts the #2 Turnover Margin per game at +1.2 - on the back of the #4 overall takeaway/gm at 2.5 (Again... not the mark of a terrible defense)
At the end of the day people will look at it how they chose. I get it. I am a defense guy myself. I LOVE seeing smothering dominant defense. So I will have to keep the big picture in mind as well. What I cannot argue with however is the above stats that to me shows that Chinander's defense is much better than a superficial glance would suggest.
