A total of 9 missed games from that starting defense dating back to the beginning of 2011. And for those of you who didn't know, they have the exact same starting defense.
By contrast, Pats have 8 this season:
(4 from Gregory, 2 from Hightower, 2 from Jones)
That number can be higher if you want to include Dennard and Chung (who was the starter).
