wist, the thing I can't understand is this whole defensive play calling thing. Apparently, there are rules that only one guy on defense can wear the headset in his helmet. But then does that guy have to play all the snaps? What if he gets hurt?

In the first game Jones wore the headset and played every defensive down. In the second, Hawk wore it and played every down.

Is our defense so complicated and dependent on schemes and personnel groups that it would fall apart without communicating on the headset? Stubby is big on cross training guys, can't he have Burnett or Shields or Tramon or Matthews wear it and call defensive signals? Are we forever tied to Jones or Hawk?
