The goal, ultimately, is not about how many points you give up....it's about outscoring the opponent.
It's fascinating how different sports view analytics. Basketball, another "ball and net", alternate possession sport, figured out years ago that possession based statistics were more insightful than counting stats. In football, it's drives we are concerned about, yet we don't readily track those stats. At best, the box score may track per play stats, but that's a bit misleading if what we are really after is per drive stats.
UCF's defense last year is not impressive from a counting stat viewpoint, but it was very effective from a drive based efficiency viewpoint. Turnovers certainly played a big part in that, and I'm always suspicious of teams that rely too much on the bounce of the ball. What they teach, though, translates to any defense you'd want to play....play with leverage, play fast and aggressive, and bring a lot of people to the ball.
We saw a glimpse of that in the spring game, enough of which to expect a massive improvement from where we were at.
