Another stat I think is useful to look at is yards per point margin, which essentially compares how many yards your offense needed to gain before scoring a single point against how many yards opposing offenses needed to gain before scoring a single point. Positive values indicate your offense needed to gain fewer yards to gain a single point whereas negative values indicate the opposing offense needed to gain fewer yards to gain a single point. The yards per point margin statistic encompasses a lot of other statistics as well, as turnovers, special teams, plays, and penalties all make it easier/harder to score points.
Nebraska ranks #118 in yards per point margin at -8.4, meaning we've had to gain 8.4 more yards than our opponent in order to score a single point. However, Nebraska ranks #33 in yards per game at 464.5 yards allowed per game and #28 in yards per game allowed at 324 yards allowed per game. I commented earlier about the strong correlation between yards per game and points per game; the same holds true for yards allowed per game and points allowed per game. So, if Nebraska ranks highly in yards per game and yards allowed per game, and both those values are strongly and positively correlated with points per game and points allowed per game, why does Nebraska rank so low in yards per point margin? It's because Nebraska isn't capitalizing on the offensive opportunities through failing to convert in the red zone and turnovers, and is making it too easy for opposing offenses to score either via a shorter field (special teams & turnovers), giving up costly penalties, or allowing the explosive play.
The two losses haven't come because we were anemic on offense or non-existent on defense. They've come because Nebraska has failed to convert on the 3rd and 4th & shorts, missed red zone opportunities, have turned the ball over, and allowed opposing teams a shorter field or have given up scores on special teams. I think those are all very teachable; the losses feel bad because they wouldn't have been losses had it not been for a handful of plays (a missed field goal against CU, failing to convert on 4th & 2, dropping a pass on 3rd & 19 that would have moved the chains, allowing a punt return for a TD, getting called for pass interference on 3rd & 9 and then allowing 3 straight 3rd & 9 conversions).
