I believe that this defense has improved each year of this run with many numbers bearing this out. Total tackles: 2011-1131 (75.4 per game), 2012-1002 (66.8 per game), 2013-486 (60.8 per game) and obviously fewer tackles is a possible indicator that the defense is getting off the field more quickly each year. Thus, 3rd down conversions allowed: 2011-37%, 2012-29%, 2013-24%. These numbers are possible indicators of increasingly effective play on 1st and 2nd downs thus: percentages in all plays during which a tackle was made (no scoring, penalties or turnovers) that went for negative yardage (sack or tackle for loss), 2011-11%, 2012-13%, 2013-16%. Average per rush allowed: 2010-4.6, 2011-3.5, 2012-3.0, 2013-2.6. Not too shabby. PPG are up slightly but I would attribute this to playing the former Big 12 champs and a really good (at the time) UNI offense. Keep it up Defense
