Another random thought, but it's pretty obvious that the defense kind of mailed it in at points during the regular season.
They were awesome in both playoff games and played like they did over the first half of the year, and were even surprisingly solid against the run. Part of that was LVE and Hankins coming back, but it's also pretty obvious that they simply lost focus/motivation at times, particularly against the Texans but also against the Packers and even the Colts before the barrage of turnovers in the 4th.
Either way, it was good to see them getting back to how they played earlier in the year, especially since it seems like Quinn should be back.
