Of 420 defensive snaps played over the last six games, the Patriots have been in sub packages (which call for at least one extra player in the secondary) a staggering 377 times. That means they were only in their base or goal-line defense on just 43 snaps over the last six games

As has been the case since 2010, Sub is the new “base” and why we now call the 34/43 “regular”. Regular is a run-stopping package. So when next summer when the 3-4 vs. 4-3 is a major topic of conversation, ignore the noise. It’s really just the defense that BB teaches from.
